Accretion and differentiation of rocky planets from interdisciplinary perspectives

Session ID#: 160811

Session Description:
The accretion and differentiation of terrestrial planets set the initial conditions for the evolution of their cores, mantles, and atmospheres. Understanding formation of terrestrial planets requires comprehension of a complex series of processes starting from primordial gas and dust in the protosolar disk, moving through protoplanets, and ending with giant impact stages of planetary formation. Recent advances in astrophysical models along with analytical and experimental geo-/cosmochemistry have been used to develop integrated models that constrain temporal and spatial scales of planetary accretion and differentiation. For this interdisciplinary session we invite contributions based on the analysis of terrestrial and extraterrestrial materials, experiments, numerical modeling, and results from planetary missions that address several aspects of protoplanetary and planetary accretion and differentiation, including, but not limited to, pebble and collisional growth of planetesimals and planetary embryos, giant impacts, satellite formation, core-mantle differentiation, magma ocean crystallization, late accretion, and volatile delivery.
