Scientific paper

Large scale anticyclonic vortices concentrate solid material in disks and may thus behave as a route for fast planet formation. The debate over their 3D stability in recent years has lead to the conclusion that they are stable to 3D perturbations provided there is a baroclinic feedback operating. In this contribution, I show how such baroclinic instability interacts with the magneto-rotational instability. Our results indicate that vortices do not survive magnetization, and therefore should exist only inside the dead zone.
