Abstract

A self-similar solution for the vertical structure of a thin accretion disk - apart from thermal equilibrium - is described. The main assumptions made are that the energy loss is due to radiation and that throughout the disk the Rosseland mean of the opacity can be fitted by the same power-law dependency on density and temperature.

Key words: accretion, accretion disks hydrodynamics
