Talk Title: History Of The Solar Nebula And Planet Formation From Paleomagnetic Measurements Of Meteorites
Abstract:
History of the solar nebula and planet formation from paleomagnetic measurements of meteorites A key stage in the formation of planetary systems is the formation of a protoplanetary disk containing a gaseous nebula. Theoretical studies suggest that magnetic fields mediated the global evolution of protoplanetary disks by transporting angular momentum and driving disk accretion. However, the nature and history of nebular magnetic fields have been poorly constrained. Here I review recent advances in our understanding of the magnetism of the solar nebula as inferred from meteorites. I discuss the implications of these measurements for the mechanism and rate of planetary accretion, the formation the first solids, the dispersal time of the nebula, and the formation mechanisms of giant planets.
