Alfvén waves damping in protostellar disks providing a way to expand the action of the magneto-rotational instability
Abstract
In order for the magneto-rotational instability to take place, we need a sufficiently ionized disk. Here, we study, besides viscous dissipation, another heating mechanism for the disk that involves the damping of Alfvén waves due to its interaction with dust grains.
