QPO frequencies and mass-outflow rates in black hole powered galactic microquasars

For all available pseudo-Schwarzschild potentials, we provide a non-self-similar model of coupled accretion-outflow system in connection to the Quasi Periodic Oscillation (QPO) of the black hole powered galactic microquasars and the emergence of barionic jets out of these objects. We use the vertically integrated 1.5 dimensional model to describe the disc structure where the equations of motion are written on the equatorial plane of the central accretor, assuming the flow to be in hydrostatic equilibrium in the transverse direction. First we formulate and solve the equations governing axisymmetrically rotating, advective, multi-transonic black hole accretion which may contain the Rankine Hugoniot Shock Waves (RHSW), and then we calculate the associated QPO frequencies νQPO in terms of relevant accretion parameters. We then argue that the post-shock region for such flows may serve as an efficient source of outflow generation; and we calculate, for same set of accretion parameters used to calculate the νQPOs, what fraction of the accreting material, denoted by Rṁ, is being blown as shock generated outflow. In this way we theoretically study the relation between νQPOs and Rṁs for galactic microquasars and compare our theoretically obtained result with observational data.
