Large-scale hydrodynamic instabilities in protoplanetary disks
Channel: MinKaiLin
Date: 2013-04-28

This is a talk I gave at MIT and Harvard in April 2013. I discuss the relevance of the `Rossby wave instability' to protoplanetary disks and planet formation. In particular, I discuss generalizing the original description of the RWI to 3D adiabatic disks. In the second part, I discuss the `gravitational edge instability' and its relevance to planet migration in massive disks, with implications for planet formation on wide orbits by disk fragmentation.
