GP012:
Planetary Magnetism and Paleomagnetism





Session ID#: 22064

Session Description:
Paleomagnetic measurements of planetary materials, spacecraft magnetometry, and planetary dynamo modeling provide insight into the understanding of the interior structures and thermal evolution of solar system bodies. At least seven bodies in the solar system have active dynamos. Mars and the Moon had ancient dynamo fields. A growing number of planetesimals are shown to have generated magnetic fields in their early history. Some meteorites likely record early fields associated with the protoplanetary disk or Sun. Many other bodies do not have active dynamos and some meteorites are unmagnetized. This session calls for contributions relating to three complementary aspects of magnetism on planets and their moons: 1) Paleomagnetism and rock magnetism of meteorites, returned samples, and their analogs; 2) Spacecraft measurements of dynamo fields, crustal magnetism; 3) Developments in dynamo theory from experiments to numerical simulations.
