Abstract
We examine highly super-Eddington black-hole models for SS 433, based on two-dimensional hydrodynamical calculations coupled with radiation transport. The super-Eddington accretion flow with a small viscosity parameter,
\alpha = 10^{-3}, results in a geometrically and optically thick disk with a large opening angle of \sim 60^{\circ} to the equatorial plane and a very rarefied, hot, and optically thin high-velocity jets region around the disk.
The thick accretion flow consists of two different zones: an inner advection-dominated zone and an outer convection-dominated zone. The high-velocity region around the disk is divided into two characteristic regions, a very rarefied funnel region along the rotational axis and a moderately rarefied high-velocity region outside of the disk. The temperatures of \sim 10^7 K and the densities of \sim 10^{-7} g cm^{-3} in the upper disk vary sharply to \sim 10^8 K and 10^{-8} g cm^{-3}, respectively, across the disk boundary between the disk and the high-velocity region. The X-ray emission of iron lines would be generated only in a confined region between the funnel wall and the photospheric disk boundary, where flows are accelerated to relativistic velocities of \sim 0.2 c due to the dominant radiation-pressure force. The results are discussed regarding the collimation angle of the jets, the large mass-outflow rate obserevd in SS 433, and the ADAFs and the CDAFs models.
