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. The luminosity in these solutions increases with the accretion rate, while the mean photon energy decreases. At the highest accretion rate, the luminosity reaches a few percent of the Eddington luminosity, while the photon energies are approximately 50 keV.
