Radiation hydrodynamic calculation of super-Eddington accretion disks

The results of nonrelativistic radiation-hydrodynamic calculations of axisymmetric supercritical accretion disks around Newtonian quasi-black holes are reported. Anisotropic and isotropic constant kinematic viscosity models are used, with radiation transport described by a gray Thomson scattering opacity and flux-limited diffusion. The resulting solutions have four distinct zones: (1) centered on the disk midplane is a thick, dense region of turbulent convection; (2) above this is an accretion zone in which low angular momentum matter rapidly flows onto the black hole; (3) the accretion zone is bounded by a photocone, in which the matter becomes optically thin; (4) inside the photocone, surrounding the angular momentum axis, is a broad subrelativistic jet of expelled matter. Applications of these results to SS 433 and to extragalactic jets are discussed. 44 references.
