| Session Description | “Isotope Ratios across the Solar System” Session will address recent advances in isotope compositions and ratios in different Solar System objects and reservoirs. Isotopes in the Solar System display temporal and sun-distance location heterogeneities. Isotope composition and ratios of planetary bodies (planets, satellites and primitive bodies) convey a unique record of the processes that formed the Solar System and planetary bodies. Their tracers and ratios constituye a powerful diagnostic tool and offer a key to reconstruct the physical and chemical conditions of the early solar system and to unravel the complex dynamics and chemistry associated with the formation and evolution of planetary bodies. Scientific investigations include, but are not limited to, isotopic measurements in planetary bodies, processes of enrichement in Solar System material, progress in modeling of isotope variations in the solar system, astrophysical implications, origin and evolution of atmospheres and oceans, and instrumental and technique developments. Recently, synergies between ground and space-based measurements together with models are leading to significant progress in the field. These studies shed lights on the origins and formation of planetary bodies, our solar system and extra solar ones. |
