Advection-Dominated Accretion Model of Sagittarius A and Other Accreting Black Holes

Abstract

Viscous rotating accretion ows around black holes become advection-dominated when the accretion rate _ M is su ciently low. Most of the accretion energy in such ows is stored within the gas and advected radially inward. The temperature is therefore very high, and much of the radiation comes out in hard X-rays and -rays. We have constructed an advection… (More)
