P52B:
Revealing the Origins of our Solar System and Its Organic Compounds Through Analysis of Meteorites and Related Planetary Materials I


Submit an Abstract to this Session


Session ID#: 60227

Session Description:
Laboratory studies of cosmic dust, meteorites, asteroids, and comets expand our understanding of the chemical and geophysical origins of our Solar System. Such studies provide essential constraints for geophysical models of planetary nebulae, accretion and differentiation of planetesimals, and the origin and diversity of organic compounds. Furthermore, comprehending the organic complement of extraterrestrial objects can help distinguish false positives when searching for indigenous biosignatures. This session invites papers related to the analysis of meteorites and other similar planetary materials that advance our understanding of the origin and evolution of our Solar System and extraterrestrial organic compounds. Topics include radiative and geochemical processes active in the early solar nebula; the timing, location, and genetics of planetary accretion and differentiation; connecting astronomical observations with laboratory data of meteorites, returned samples, and analog materials; and the origin and evolution of organic molecules found on asteroids, comets, and their fragments.
