Numerical general relativistic radiation-hydrodynamics of accretion flows. |

Abstract |
I will discuss the progress in the numerical modeling of accretion flows made possible after solving the general relativistic radiation-hydrodynamics equations through the moment formalism and with Godunov-type methods. I will first present the necessary numerical tools for coping with the stiffness of the source terms in the equations and for treating the intermediate regime between the optically thick and the optically thin. Then, I will show some applications to spherical accretion and to supersonic Bondi-Hoyle accretion onto a black hole, discussing its astrophysical relevance. |
