Giant Planet Interiors
Session ID#: 161075
Session Description:
New constraints to the present-day interior structure and dynamics of giant planets are critical to advance our understanding of the formation and evolution of planets in the solar system and beyond. The Juno and Cassini missions have recently revealed key aspects of the interiors of Jupiter and Saturn from a wealth of new measurements. Further, new studies of Uranus and Neptune continue to highlight the relevance of ice giants in understanding the exoplanet population. This session will bring together theory and observations capable of advancing our understanding of giant planet interiors. We welcome submissions within a broad range of topics, including: ring and Doppler seismology, gravity fields, normal mode oscillations, zonal flows and differential rotation, dynamo magnetic fields, core detection and characterization, consequences of stable stratification, helium and heavy element bulk composition, formation scenarios, and evolutionary pathways. We welcome abstracts either focusing on a single planet or comparing multiple bodies.
