THE MECHANISM OF ANGULAR MOMENTUM TRANSFER IN ACCRETION STELLAR DISKS BY LARGE VORTICAL STRUCTURES

A. Lugovskiy, V. Chechetkin, K. Sychugov

Анотація


Large-scale vortical flows arising in shear flows of stellar accretion disks with Keplerian azimuthal velocity distributions is investigated. The two reasons of the development of large-scale instability is shown: hydrodynamical instability and magnetorotational instability (MRI). The presence of large-scale structures leads to angularmomentum redistribution in the disk.
