Supercritically accreting stellar mass black holes as ultraluminous X-ray sources
Supercritically accreting stellar mass black holes as ultraluminous X-ray sources
We derive the luminosity–temperature relation for the supercritically accreting black holes (BHs) and compare it to the data on ultraluminous X-ray sources (ULXs). At super-Eddington accretion rates, an outflow forms within the spherization radius. We construct the accretion disc model accounting for the advection and the outflow, and compute characteristic …
