摘要：The galactic microquasar SS 433 is a super-critically accreting black hole candidate and their relativistic jets have been interpreted to originate in the acceleration by the radiation pressure in the inner accretion disk. Based on the initial 1D models of supercritical accretion disk with mass loss and advection, we examine the disk and jets of SS 433 with ˙M =103 ˙Mc by two-dimensional radiation hydrodynamical calculations. Depending on the viscosity parameter a, we obtain the total luminosities more than 10 times higher than the Eddington luminosity, the jets mass-outflow rates of 10 􀀀6 – 510 􀀀5Myr 􀀀1, and the wind mass-outflow rates of 10 􀀀6 – 10 􀀀4Myr 􀀀1, which are generally compatible with the observed rates of SS 433. In addition, for a case of large viscosity parameter a, we find a new type of instabilities of the accretion rates near the inner edge and the disk luminosity. These instabilities grow into recurrent hot blobs which develop outward and upward, and result in QPOs of the total luminosity with an amplitude of a factor 1 – 2 and a quasi-period of 30 sec. This may explain a massive jet ejection and QPOs-like phenomena observed recently in SS 433.
