Radiation of accretion disks in quasars and galactic nuclei

The continuum spectra of accretion disks around supermassive Schvarzshild black hole are calculated for a set of accretion disk parameters. In every point of the disk surface the atmosphere is considered to be similar to the atmosphere of the star with the same values of the surface gravity and effective temperature. All important effects of general relativity affected the spectrum shape are taken into account.
