Stability of Magnetically Supported Disks
Abstract
Cold, magnetically supported disklike clouds are evolutionary precursors of protostars. Magnetic tension balances self-gravity in these systems, so the magnetic field lines kink as they cross the disk. Despite this strong magnetic curvature, these disks turn out to be marginally stable to self-gravitating perturbations which preserve the plane of the disk.
