Scientific paper

A study is presented of gas flow above an alpha disk by solving the equations of their motion when acted upon by radiation pressure from the disk and by the gravitational attraction of its central object. When the disk luminosity is 0.4 times the Eddington luminosity, almost all material is ultimately accepted by the central object. The Eddington number range is specified for gas streaming away along the rotation axis of the disk, and conditions are defined for a strong outflow along the axis, noting that clouds form in this stream due to an oscillation generated by the radial radiation force field near the central object.
