Scientific paper

In this paper, an exact solution of the gray, scattering, radiative transfer problem in a dynamically evolved thick accretion disk is given. The collimation of the radiation field in the polar regions is demonstrated, and the ratio of radiative to gravitational acceleration is found everywhere. It is shown in detail how these specific dimensionless calculations can be scaled to physical disks of interest. The calculations reported here have been done with a totally reflecting inner boundary condition, which is shown to enhance the radiation anisotropy over the perfect absorber condition.
