Accretion onto a moving black hole: a fully relativistic treatment

The effect of constant-rate motion through a uniform adiabatic medium on the steady-state accretion of matter onto a Schwarzschild black hole is investigated theoretically by means of numerical simulations. The derivation of the model is given in detail, and the results are presented in extensive gr...

Zusammenfassung:	The effect of constant-rate motion through a uniform adiabatic medium on the steady-state accretion of matter onto a Schwarzschild black hole is investigated theoretically by means of numerical simulations. The derivation of the model is given in detail, and the results are presented in extensive graphs. The appearance of the flows and the accretion rates are found to be in good agreement with published data for the Newtonian regime and generally similar for the relativistic case. 28 references.
