 note = {Astrophysics with All-Sky X-Ray observations: 3rd International MAXI Workshop (RIKEN, 10-12 June 2008), We perform global two-dimensional radiation hydrodynamic (RHD) and radiation magnetohydrodynamic (RMHD) simulations of accretion flows around black holes. Our RHD simulations reveal that the steady, supercritical accretion is feasible. The disk luminosity is several times larger than the Eddington luminosity. The disk is geometrically and optically thick. It is supported by the radiation pressure. The strong radiation pressure force drives the outflow above the disk. Our RMHD simulations demonstrate three distinct modes of accretion. When the density is large, a thick, very luminous disk forms. When the density is moderate, the accreting gas can effectively cool, thus generating a thin disk. When the density is too low for radiative cooling to be important, a disk becomes hot, thick, and faint. Strong outflows emerge, which are driven either by radiation pressure force for the dense disk or magnetic pressure force for the less dense disks., Physical characteristics: Original contains color illustrations, 資料番号: AA0064306030, レポート番号: JAXA-SP-08-014E},
