Numerical simulations of relativistic wind accretion on to black holes using Godunov-type methods
Jose A. Font, Jose M. Ibanez, Philippos Papadopoulos
We have studied numerically the so-called Bondi-Hoyle (wind) accretion on to a rotating (Kerr) black hole in general relativity. We have used the Kerr-Schild form of the Kerr metri…
