General relativistic radiation hydrodynamics of accretion flows - I. Bondi-Hoyle accretion
We present a new code for performing general-relativistic radiation-hydrodynamics simulations of accretion flows onto black holes.The radiation field is treated in the optically-thick approximation, with the opacity contributed by Thomson scattering and thermal bremsstrahlung.Our analysis is concentrated on a detailed numerical investigation of hot two-dimensional, Bondi-Hoyle accretion flows with various …
