Accretion onto Black Holes. II

The paper is a continuation of a review of accretion phenomena in systems with black holes. A Roche lobe, disk accretion onto a black hole, a standard solution for an accretion disk, optically thick and optically thin models, emission spectra of accretion disks, mechanisms of turbulence excitation, advective disks, the Blandford–Znajek process are considered.
