Abstract
Whitepaper #056 submitted to the Planetary Science and Astrobiology Decadal Survey 2023-2032. Topics: other planetary bodies: Dust; primitive bodies; solar system formation, dynamics processes, and chronology
Highlights
Introduction and Open Science QuestionsSub-millimeter sized dust grains are present throughout the solar system as both interplanetary dust (IDP) and interstellar dust particles (ISD)
In the outer solar system, roughly beyond the orbit of Jupiter, models suggest that IDPs are most likely dominated by sources in the Edgeworth-Kuiper Belt with additional minor contributions from Oort Cloud comets and active Centaurs [Liou and Zook, 1999; Han et al, 2011; Szalay et al, 2013; Piquette et al, 2019; Poppe et al, 2019; Poppe, 2016, 2019]
ISD connect the history of our solar system to planetary systems forming around other stars [e.g., Sterken et al, 2013; Westphal et al, 2014; Altobelli et al, 2016]
Summary
Our solar system’s debris disk provides “ground-truth” comparison to the multitude of observations of exozodiacal debris disks around other stars [e.g., Trilling et al, 2008; Bryden et al, 2006, 2009; Koerner et al, 2010; MillanGabet et al, 2011; Montesinos et al, 2013; Eiroa et al, 2013; Chen et al, 2014; Kral et al, 2017; Hughes et al, 2018; Ertel et al, 2018], where hidden planets may warp and/or perturb their debris disks in manners similar to how Neptune and/or Jupiter may affect the equilibrium distribution of interplanetary dust in our solar system [e.g., Liou and Zook, 1999; Moro-Martín and Malhotra, 2002; Holmes et al, 2003] Despite these broad, crosscutting implications for planetary science, we still do not fully understand the dust grain spatial and velocity distributions sourced from various parent bodies, or the variability of the chemical compositions of interplanetary and interstellar dust grains throughout our solar system. A comprehensive experimental effort to explore the composition and dynamics of interstellar dust particles flowing through our solar system has not yet been accomplished
