DI006
Formation, Structure, and Evolution of Planet Interiors
Session ID#: 248784
Session Description:
The diversity of sizes, compositions, and interior structures of the confirmed planets in our Galaxy poses a fundamental challenge to our understanding of planetary formation and evolution. Planetary processes such as planetesimal/protoplanet growth, giant impacts, differentiation, thermal evolution, and magnetic field generation operate under a wider range of conditions in exoplanetary systems than in our own Solar System. This session aims to bring together the latest geophysical, geochemical, astronomical, and material properties perspectives on the formation, structure, and evolution of planetary interiors. We welcome interdisciplinary studies that link observational constraints, high-pressure/high-temperature material and transport properties, and models of planetary formation and structure. By fostering exchanges between studies of metal- and rock-rich terrestrial planets and volatile-rich sub-Neptunes and ice giants, this session will highlight how insights from one field can inform another and advance a synergetic understanding of the solar system planets and exoplanets.
