Scientific paper

Models of stationary axisymmetric accretion of gas revolving according to Kepler's law with a predominance of radiation pressure over gas pressure are developed. It is shown that the bipolar outflow of gas in these models cannot correspond with accretion. The critical value of the Prandtl number analog, which separates axisymmetric and spherically symmetric accretion, is calculated. The axisymmetric flow in the models is analzed and compared with the analogous flow in models with a predominance of gas pressure over radiation pressure.
