The dynamics of planets and planetesimals in turbulent protoplanetary discs

Séminaire IPAG de Richard Nelson (Queen Mary, University of London), jeudi 7 avril 2011 à 11h00, IPAG seminar room

In this talk I will present recent results concerning the dynamical evolution of planetesimals and planets embedded in protoplanetary discs. The talk will focus in particular on the dynamical stirring of planetesimals in discs with and without dead zones, and the implications for the collisional growth of these bodies, and their radial diffusion throughout the disc during the planet formation epoch. I will also present recent results of simulations that examine the migration torques experienced by low mass planets embedded in turbulent discs, with particular emphasis on the corotation torque.
