Scientific paper

The influence of the self-gravity of a geometrically thin disk on a geometrically thick atmosphere corona above the disk around a central object is examined. As a self-gravitating disk, Toomre's model is adopted. The torus is constructed under the assumptions that the specific angular momentum is constant in whole space and that the gas is assumed to be polytropic and has no motion in the meridional plane. Although the potential of self-gravity compresses the gas to the equator in the bottom region, at the region where the density of gas is low, this effect is not remarkable.
