Planetary Magnetism and Protoplanetary Disk Magnetism

Session ID#: 157235

Session Description:
Magnetic fields of various origins allow for the study of the internal structure and geologic history of planetary bodies, and the evolution of the early solar system. Magnetic data are typically available from satellites, meteorites, or from surface measurements. In this session we welcome contributions that cover observational, experimental, and theoretical investigations (including method development) of the magnetosphere, crustal magnetism, core dynamics, protoplanetary disk magnetism and other planetary-body internal magnetic sources.
