Session ID#: 48757

Session Description:
Planetary magnetism provides a window into the evolution of planets, moons, and early planetesimals from exosphere to core. At the same time, investigating the composition, dynamics, and thermal evolution of planetary cores is also critical for predicting the behavior and evolution of dynamo fields.  In this session, we aim to foster interdisciplinary conversations between investigators studying magnetics and planetary interiors.  As such, this session calls for contributions relating to observational, experimental, and theoretical/modeling work in the areas of: 1) core composition; 2) core dynamics; 3) planetary thermal evolution; 4) dynamos; 5) crustal magnetism; 6) paleomagnetism; 7) magnetospheres.
