New solutions are presented for spherical accretion onto a black hole, which are self-consistent in the sense that the infalling gas itself emits the radiation which controls its thermal profile. In these solutions, radiative cooling dominates in the outer part of the flow, and Compton heating by X-rays becomes important when the gas is already supersonic.
