About this Event
Planets are thought to form via core accretion of molecular gas and dust in circumstellar disks around protostars. Discovery and characterization of exoplanets can challenge, refine, and generalize our understanding of the dynamics and size distribution of pebbles and planetesimals. For example, existence of close-in Jupiters requires a migration mechanism either via angular momentum exchange with the protoplanetary disk or tidal circularization of eccentric orbits.
