Scientific paper

The properties of the spacetime consisting of a Schwarzschild hole distorted by a self-gravitating thick disk are discussed, and the metric coefficients are determined. The calculation of the metric coefficients is performed under the assumption that the ring is static and is symmetrically placed in the equatorial plane around a Schwarzschild hole. The replacing of the rotating disk by a static ring is shown to be justified for disk/hole mass ratios of less than 1. It is noted that in the presence of self-gravity the lowering of the Keplerian distribution of the angular momentum near the center of the disk implies that the binding energy release will be higher, causing the temperature to be higher.
