Colloquium: Are magnetic fields shaping protoplanetary discs?

Prof. Geoffroy Lesur (Grenoble, France) will introduce us to non-ideal magneto-hydrodynamical (MHD) disc models, and their impact on planet formation.

Over recent years, our understanding of protoplanetary disc (PPD) dynamics have changed dramatically. It is now believed that MHD processes are playing a very important role in the formation and evolution of these objects. While a direct measurement of magnetic fields in PPDs is still lacking, I will show in this seminar that several observed features can easily be explained as a natural consequence of magnetised discs. In this context, I will revisit the problems of grain transport and accumulation, disc clearing and planet migration.
