Query: Numerical simulations of self-gravitating magnetized disks   We present the first global simulations of self-gravitating magnetized tori.
The simulations are performed with Zeus-2D and GLOBAL. We find the
magnetorotational instability (MRI) to behave similarly in a self-gravitating
environment as in previous simulations of non self-gravitating systems:
enhancement of turbulent angular momentum transport follows the linear phase.
The torus quickly develops a two component structure composed of an inner thick
disk in Keplerian rotation and an outer massive disk. We compare this result
with zero mass global simulations in 2D, and also present preliminary results
of 3D simulations.
