Abstract

In this work, at first we present a model of studying astrophysical flows of binary systems and microquasars based on the laws of relativistic magnetohydrodynamics. Then, by solving the time independent transfer equation, we estimate the primary and secondary particle distributions within the hadronic astrophysical jets as well as the emissivities of high energy neutrinos and γ-rays. One of our main goals is, by taking into consideration the various energy-losses of particles into the hadronic jets, to determine through the transport equation the respective particle distributions focusing on relativistic hadronic jets of binary systems. As a concrete example we examine the extragalactic binary system LMC X-1 located in the Large Magellanic Cloud, a satellite galaxy of our Milky Way Galaxy.

Highlights

In recent years, astrophysical magnetohydrodynamical flows in Galactic and extragalactic Xray binary systems and microquasars have been modelled with the purpose of studying their multi messenger emissions [1, 2]
By employing a C-code developed by our group here, we concentrated on performing extensive calculations for the Galactic Cygnus X-1 and the extragalactic LMC X-1 binary systems
Summary and Conclusions Black Hole X-ray binary systems (BHXRBs), consisting of a high mass compact object and absorbing mass out of a companion star that results in an accretion disc formation, have been identified through their relativistic magnetohydrodynamical astrophysical flow ejection perpendicular to the aforementioned disc

Summary

Introduction

Astrophysical magnetohydrodynamical flows in Galactic and extragalactic Xray binary systems and microquasars have been modelled with the purpose of studying their multi messenger emissions (radiative multiwavelength emission and particle, e.g. neutrino, emissions) [1, 2]. Well known microquasar systems include the Galactic X-ray binaries SS433, Cyg X-1, etc., while from the extragalactic ones we mention the LMC X-1, LMC X-3 (in the neighbouring galaxy of the Large Magellanic Cloud) [6, 7], and the Messier X-7 (in the Messier 33 galaxy). Their respective relativistic jets emit radiation in various wavelength bands and high energy neutrinos
