Identification of Z Cam’s Historical Counterpart: The Quest for an Ancient Nova

Abstract In recent astronomical discussions, attempts have been made to link the known dwarf nova Z Cam to historical celestial events, particularly the ”guest star” phenomenon reported in China in 77 BCE. Despite other suggestions and the problems with regard to the location of the event in 77 BCE, its identification with Z Cam is used in the Variable Star IndeX (VSX) of the AAVSO and in several research papers that aim to derive knowledge on the evolution of cataclysmic variables. Through the reconstruction of the super-constellation of the Purple Palace in the Han Dynasty, we found that Z Cam is actually located outside this enclosure, contradicting the records of the 77 BCE guest star being ”within the Purple Palace”. With newly found text versions of the guest star in 77 BCE, we narrowed down the position given therein. Combined with a new analysis of accompanying divination text leads to the conclusion that this guest star was actually a comet. Finally, through meticulous examination and comparison, we conclude that the guest star of 369 CE appears the most plausible candidate for Z Cam’s historical counterpart, aligning with both textual evidence and modern astronomical observations.

Does the Nebra Sky Disk encode an early Bronze Age report of a galactic supernova?

AbstractThe Nebra Disk is one of the earliest astronomical manifestations of humanity in Central Europe. We interpret the striking sevenfold stellar group shown on the disk as a celestial conjunction of the five naked‐eye visible planets together with Pollux and Castor in the constellation Gemini (happening in 2210BC) and the dominating large, filled circle as a bright supernova, probably corresponding to the remnant 3C58 in Cassiopeia. We believe that a close coincidence of these two extremely rare celestial events, that does never happen more than once in a human lifetime, could have impressed people of that epoch in a way that it was conveyed orally over several generations, until some Bronze Age artist created the Nebra Disk. If this interpretation is correct, it could offer a rather exact dating of a supernova explosion observed about 4200 years ago, more precise than any other dating methods for past supernova events, possibly leading to significant new insights into the underlying physics of supernovae.

Solar bird banding: Notes on changes in avian behavior while mist-netting during an eclipse

Solar eclipses present rare celestial events that can elicit unique behavioral responses in animals, yet comprehensive studies on these phenomena, particularly concerning bird behavior, remain limited. This study, conducted at the Red Butte Canyon Research Natural Area in Utah during the annular solar eclipse on October 14, 2023, aimed to document and analyze avian activity using bird banding data. Leveraging 11 years of banding records, we observed a surprising positive peak in bird captures, indicating increased activity during the eclipse, challenging conventional expectations of decreased activity during peak totality. The unexpected, record-breaking captures on the eclipse day at this location, which also surpassed the average trend in captures over time for 18 other banding days in mid-October, highlights the complexity of bird behavior during celestial events. This study marks the first known published effort to conduct bird banding during a solar eclipse. Quantitative analyses, including species composition and capture trends, contribute to a nuanced understanding of avian responses to the eclipse. This study underscores the importance of empirical research in unraveling the intricacies of how birds navigate and adapt to unique environmental conditions created by solar eclipses.

Rejuvenation of an ancient observatory in southern India

A change in policy that has allowed the public to use the Thiruvananthapuram Astronomical Observatory has brought about a consistent increase in visitors that is being spurred on by recent celestial events, such as the appearance of comet C/2022 E3 (ZTF).

In this article, we publish a fragmentary clay tablet from the Sippar Collection in the Cuneiform Tablets Archive of the Istanbul Archaeological Museums, inventoried under the museum number Si 735. The tablet seems to record, in literary language, the ruminations of a man about a female slave who had given birth to his son. Due, however, to the tablet's poor state of preservation, many aspects of this unusual text remain unclear. After introductory remarks on the nature of the tablet and a brief discussion of the above-cited "Sippar Collection," we provide an edition of the text, together with notes on its orthography, language, structure, and genre, as well as a philological commentary.

Basing herself on the archives of several Parisian institutions, A. highlights the involvement of the French consular official and epigraphist Charles Clermont-Ganneau (1846–1923) in this process, first in acquiring the pieces of the stone which had been smashed by Bedouins shortly after its discovery in situ by A. F. Klein and selling these to the Louvre and then working himself at the Louvre on the reconstruction of the stela (a project he brought to successful completion in 1875) on the basis of drawings and a tracing of the still intact artifact which he had commissioned several Arab workers to carry out prior to its destruction.—C.T.B. 34.

The Social Effects of an Awesome Solar Eclipse

Astronomical events such as solar eclipses have played a transformative role in human social collectives as sources of collective wonder, inspiration, and reconciliation. Do celestial phenomena systematically shape individuals and their groups? Guided by scientific treatments of awe as an experience that helps individuals form into collectives, we used Twitter data (N = 2,891,611 users) to examine the social impact of a historic, awe-inspiring celestial event: the 2017 solar eclipse. Relative to individuals residing outside the eclipse’s path, individuals inside it exhibited more awe and expressed less self-focused and more prosocial, affiliative, humble, and collective language (Study 1). Further, individuals who exhibited elevated awe surrounding the eclipse used more prosocial, affiliative, humble, and collective language relative to their preeclipse levels and relative to users who exhibited less awe (Study 2). These findings indicate that astronomical events may play a vital collective function by arousing awe and social tendencies that orient individuals toward their collectives.

Time, Eigenvelocity, and Propulsion of Celestial Bodies – On Barnard’s Star

The measured time interval of celestial events is t, and t is only Earth time, not the original time t of celestial events. , the Earth time t must be converted into the original time t of the celestial event. Measure the radial velocity u of a celestial body, it is not the eigenvelocity of the celestial body, the eigenvelocity is constant, but the apparent velocity changes, the celestial body moving towards the solar system is the blue-shifting celestial body, and the apparent velocity of the blue-shifting celestial body, year-on-year ratio One year slow. Barnard’s Star is a blue-shifting celestial body, which is an example. The apparent velocity is slowing down every year. The apparent velocity of the first measurement is 110.8km/s, (ARICNS: 1916), and the apparent velocity of the second measurement is 110.8km/s. It is 106.8km/s (SIMBAD: 2000). From this paper, it is calculated that the intrinsic velocity of Barnard’s Star is 959.332km/s, and the apparent velocity in 2022 is 105.751km/s.

Interface dynamics with heat and mass fluxes

Unstable interfaces ubiquitously occur in fluids, plasmas and materials, from the celestial event of supernova to the atomic level of plasma fusion. Knowledge of their fundamentals is in demand in science, mathematics, and engineering. Our work considers the classical problem of stability of a phase boundary having heat and mass fluxes across it and yields a rigorous theory resolving challenges not addressed before. By employing self-consistent boundary conditions for thermal heat flux, by identifying the perturbation waves' structure, and by thoroughly investigating the dependence of waves' coupling on system parameters, we discover new fluid instabilities in the advection, diffusion and low Mach regimes. We find that the interface stability is set primarily by the interplay of macroscopic inertial stabilization with destabilizing acceleration, and the microscopic thermodynamics and thermal heat flux creates vortical fields in the bulk.

Risk and cost benchmarking of solar energy technology based on celestial phenomenon for a power market integration

Intermittency associated with the renewable energy institutes various uncertainty with respect to power market perspective. To overcome the uncertainties associated with the renewable energy source a novel benchmarking approach is proposed. The benchmarking is done in order to compare the economical perspective of various energy sources. The celestial events considered for benchmarking are Aphelion, Perihelion, and solstice (directly affects solar irradiance). The proposed method can determine the harvest quality of solar farming based on profit returns. The solar energy output data provided by the National Institute of Wind Energy (NIWE) has is used to find out the solar energy output during Aphelion, Perihelion, and solstices. For benchmarking of an area, Levelized Cost of Electricity (LCOE), Conditional Value at Risk (CVaR) and carbon pricing index, have been considered. Levelized Cost of Electricity (LCOE) is used to determine the cost of solar energy produced during its lifetime, and CVaR is used to assess the tail-end risk for the profit return. Carbon pricing is benchmarked to understand the environmental impact of the energy sources. The duration chosen is 10.00–14.00 h which is the time of the peak solar irradiances considering a solar thermal and PV system. IEEE 5 and 14 bus systems are chosen for the case study. Based on the results obtained, market condition influences the LCOE. The LCOE is lower for stable market returns and higher for an unstable market. On comparing the benchmark scores considering the best case scenario, solar thermal is having 59% higher LCOE, 5.2 times higher carbon price index and 42% higher CVaR than PV system. Thus the proposed approach will help market participant in decision making related to the profit and risk associated with the renewable energy.

Paleolithic Women’s Spirituality and its Relevance to us Today

In this paper, I consider Paleolithic women's spirituality as expressed through various aspects of their artwork found in the caves of Spain and the ‘Venus figurines and suggest these icons may be seen as an attempt by some of early these women artists to translate their own inner experiences and insights cataphatically, and thereby reconcile the tension between the image-less I experience ineffable transcendence using didactic expression grounded in images. This method was used later by the Spanish mystic Santa Teresa, who clearly felt the mystery needs to be related to personally; it is not an abstract mystery, but a mystery that is alive, that vibrates through us and is what animates every cell in our body; we are an embodiment of this living mystery. Whereas in the 16 Century it was normal for Teressa to consider the mystery as God, it was most likely customary for Paleolithic women to think of the mystery as the Universal or Great Mother, an insight some of them probably arrived at through analogy with the creative force expressing itself through their pregnant bodies. Whereas Santa Teresa employed images that meant something to the people living during her time, these ancient women probably did the same. From this perspective, their artwork may be seen as pointers to this 'entity' or mystery, which, is both immanent in creation and at the same time is beyond duality and all definitions. Here, I also submit that they probably realized the creative aspect of the enigma through their pregnancies, and, in their death, they recognized it as the destructive or dark phase in the cycle of life that is so necessary for ‘rebirth’ to occur, and, in its expression through celestial events, they probably celebrated it through their rituals and their pilgrimages which took place at specific times of the year.

Bi-Daily Venus in the Medieval Thought of William of Conches: Explaining an Uncommon Celestial Event by Circumsolarity

Bi-Daily Venus (BDV) is an uncommon event, occurring when an observer can view that planet twice in a single day – in the twilight of dawn and dusk. That William of Conches knew of this phenomenon in twelfth-century France is surprising given the dearth of BDV accounts. Yet following unnamed sources, he discussed BDV in three of his works: Philosophia Mundi, Glosae Super Boetium, and Dragmaticon. From the appearance of the first of these volumes (ca. 1125) to the last (ca. 1145), William’s reasoning for BDV’s occurrence changed from mild scepticism of given explanations to acceptance of Venus’s sometimes circumsolar height above the sun as the correct interpretation. This paper examines William’s evolving BDV discussions, considers what planetary height meant to William, presents an explanatory diagram, and concludes that William understood Venus to be within the ecliptic plane when BDV occurs – in contrast to our modern explanation for BDV.

A probabilistic framework and significance test for the analysis of structural orientations in skyscape archaeology

The assessment of the orientation of built structures is often hampered by the lack of historical or ethnographic records that could be used to support claims of alignments to celestial events such as the rising and settings of sun, moon or stars. This has led to an obsession with surveying large numbers of structures in order to identify patterns in orientation that might betray intentionality - however, no first-principles framework has ever been proposed and the few statistical significance tests used are of limited applicability. This paper addresses these problems by laying out a probabilistic framework for the analysis of structural orientations and using it to develop a test of statistical significance. The framework is based on two simple premises: firstly, that the measurement of a structural orientation can be modelled as a probability distribution; and secondly, that in order to assess the likelihood of celestial alignments such a distribution needs to be coordinate-transformed in a manner not unlike that of radiocarbon calibration. A method that aggregates multiple structural orientations and quantifies their statistical significance in the form of a p-value is then introduced. Finally, the robustness of the presented methodology over previous approaches is demonstrated using real-world datasets of orientations of ancient Egyptian temples and tombs and Scottish Recumbent Stone Circles, and the ensuing conclusions compared with past interpretations.

Critical study of concept of Grahana (Eclipse) in Ayurveda and jyotish science and its influence on human lives WSR to COVID-19

Objective: (1) To intimate about the concepts of Grahana as described in Jyotish Shastra and Ayurveda. (2) Brief knowledge about the facts related to the science of Jyotish for the current scenario. (3) To describe about the impacts of celestial events on human life and on present pandemic, i.e., COVID-19. Data Sources: Secondary. Review Methods: Literary method is adopted here from the available sources of Ayurveda and different Ancient Jyotish (Astrological) texts. Results: From the literature, it is observed that there are definite relations in between the eclipses of Sun and Moon on wars and pandemics. Conclusions: Effects of eclipses on pandemics were seen since a long period of time. It was observed and concluded that eclipse affects the human lives in various ways and may act as potential indicator of war and epidemics. To generate the data, there is a need to study the effects of eclipses on epidemics and wars which in turn has been told as the cause of epidemic in Ayurveda.

Complex Epithet Constructions: The North-Eastern Yakut Olonkho Telling Tradition

The present article describes complex epithet constructions, which were distinguished in the north-eastern Yakut Olonkho-telling tradition. The aim of the research is to study complex epithet constructions: epithets of comparison, numerical, and metaphoric epithets. There were a total of 251 (26%) epithets with complex comparisons found in the text in the course of its analysis. The first group comprises of epithets connected with natural objects. In Olonkho, the descriptions of the northern Yakutia territory (i.e., its plant life, water landscapes, general landscapes, and celestial events) are introduced by incorporating these epithets, which are widely used. The second group of complex epithets with comparisons comprises of somatic epithets which give a general description of the main and secondary characters through the body and appearance description as well as the gestures and emotions. The third group comprises of complex epithets, the objects of which are connected with dwellings, household dwellings, and general household features. A significant meaning of the bogatyr (ancient warrior) horse in the life of the main characters of Yakut Olonkho allows singling out a separate, the fourth group of epithets, i.e., 15 complex epithets, the objects of which are those denoting horse body parts. The north-eastern Olonkho text contained 382 instances of numbers used as component-parts of numerical epithets. The numerical epithets are subdivided into three groups. Thus, the first group, which is the largest among all three (91%) consists of numerical epithets, which in turn, include linear numerals as well as cardinal numerals and ones denoting age and number adverbs. The second group contains a smaller scope of numerical epithets (7%); these include numerical epithets based on the usage of double-digit numbers. The third and the smallest group (2%) includes numerical epithets which contain three-digit components (2%). Numerical epithets are one of the widely used epithets in the poetic structure of the epic tradition under study. Apparently, the numerals in this type of epithet constructions performed not only a comprehensive and descriptive but also an educational function. Metaphoric epithets make up 15% of the total amount of epithets identified and selected within the scope of the north-eastern Olonkho text research. They are equally simple and complex in their essence. Simple metaphoric epithets consist of one object and image. Complex epithets contain several objects, each of which has its own attributive combinations; these attributive combinations consist of a noun in its non-transferred meaning and a metaphor. Thus, epithets represented in the Olonkho texts are complex in their structure (26%).

Geographical Alignments of Megalithic Sites in Northern Europe – An Unexpected Finding

In examining the alignments of megalithic sites in northern Europe it has been determined that more than a dozen appear to point toward a geographic location near or within modern-day Paris. The earliest sites (late Neolithic) that face in this direction are not aligned with celestial events such as solstices or lunar standstills. However, later sites are oriented to celestial events as well. That these sites both reference celestial events and a specific geographic location suggests that their locations could not have been chosen at random. The probability that over a dozen sites are aligned to face a specific geo-location is extremely small. Despite the common belief that Neolithic people were organized in relatively small groups, this finding suggests they had knowledge of a larger group/higher level of organization that was connected in some way with a place of importance – a location near Paris and could align sites hundreds of kilometers away to that location.

Celestial Aspects of Hittite Religion: An Investigation of the Rock Sanctuary Yazılıkaya

Regular celestial events assumed remarkable significance for the cultic rituals of the Hittite civilisation (c. 1600-1180 BC) in central Asia Minor. Numerous texts found at the capital Ḫattusa relate to solar deities and celestial divination reminiscent of Old Babylonian astronomical and astrological practices. Here we suggest that the rock sanctuary of Yazilikaya, which was considered one of the holiest places in the Hittite kingdom, had a calendrical function. It contains more than 90 rock-cut reliefs, dating to the second half of the thirteenth century BC, of deities, humans, animals and mythical figures. The reliefs in Chamber A are arranged in groups to mark the days, synodic months and solar years. Using this system, the Hittite priests were able to determine when additional months were required to keep lunar and solar years aligned. The astronomical and astrological interpretation of Yazilikaya serves as a point of departure for a brief re-examination of celestial aspects in Hittite religion. Open Access: CC BY

Climatic issues in early modern England: Shakespeare's views of the sky

Climatic issues pervade early modern English drama, and three main reasons may be adduced for this. First, while in the first half of the 16th century Renaissance natural philosophers still felt compelled to acknowledge the accidental nature of weather‐related phenomena, in the second part of the century, new beliefs emerged and the dramatization of celestial events allowed for a more immediate access to the natural world. Second, then as now, Shakespeare's “sceptred isle” (Richard II) was often exposed to the wind, the rain and the freezing air, and such characteristics were believed to have a lasting impact on the habits of the English nation. Third, people then had to struggle against the adverse weather conditions characterized by what is now referred to as the “Little Ice Age.” As actor and playwright, Shakespeare saw the sky as a theatrical element. While his so‐called festive comedies appear far less festive if we pay attention to their climatic specificities, his tragedies offer interesting insights into the way the playwright associates heavens and humors on the one hand, climate and the planets on the other. I thus argue that climate was for Shakespeare a framing device giving coherence to his playtexts and providing the audience with a natural, elemental, and cosmic background. His interest in the way weather conditions affect human behavior prompted him to modify traditional points of view and, as a result, to foreground Man's ominous capacity to trigger climatic disorders.This article is categorized under: Trans‐Disciplinary Perspectives > Humanities and the Creative Arts

Sensational Interfaces and the Aesthetics of Space Apps

Abstract As the momentum of space exploration unfolds, our planetary exterior is increasingly transformed into a site of capitalist production and destruction. Grounded within infrastructures, processes and practices of mediation, our technological acquisition of space is also entwined back into the ambits of global media cultures down on Earth. The currents of this enculturation are indexed by the upsurge and emerging variety of “space apps” which use techno-scientific data and creative visualisation to offer assorted digital experiences of outer space-from maps and tours of planets, stars and galaxies, to real-time observation of celestial events and phenomena. To provide some measure of this inclination, we consider the ways in which these apps sculpt our collective techno-aesthetic relations with extraplanetary space. Framing their digital renderings as the sensational interface of capitalism, we suggest that they offer a glimpse into the ongoing manipulations of economies of attention and the appropriations of affect that undergird its high-tech progress in the space age.

A New Square Grid-Based Method for Identifying Solar Activities

The FITS is widely used as a common file format in astronomy. However, how to detect an effective celestial event from large-scale astronomical images with complex background is a thorny issue. This paper proposes a square grid structure for target detection (GSTD) of solar activities, inncluding the separation of the target area and the deletion of the background area. This kind of processing can greatly reduce the storage cost of the data set, while the solar activity area can be well preserved. The solar image is operated through an equally sized square grid to separate the solar activity target area and the background area to speed up the processing of images, improve processing accuracy, and effectively prevent image noise interference. The experiment results have shown that this method delivers satisfactory performance in accuracy and time-cost. Through the anti-jamming processing of image noise, the accurate positioning and effective recognition of solar activities are realized. This method has been proved to achieve good image segmentation recognition of solar phenomenon in the research of various types of solar activities. Moreover, it can provide a feasible way to reduce the storage occupancy of Content-Based Image Retrieval (CBIR) systems.
