Abstract
We examine the properties of the viscous dissipative accretion flow around rotating black holes in the presence of mass loss. Considering the thin disc approximation, we self-consistently calculate the inflow-outflow solutions and observe that the mass outflow rates decrease with the increase in viscosity parameter (α). Further, we carry out the model calculation of quasi-periodic oscillation frequency (νQPO) that is frequently observed in black hole sources and observe that νQPOmax increases with the increase of black hole spin (ak). Then, we employ our model in order to explain the High Frequency Quasi-Periodic Oscillations (HFQPOs) observed in black hole source GRO J1655-40. While doing this, we attempt to constrain the range of ak based on observed HFQPOs (∼300 Hz and ∼450 Hz) for the black hole source GRO J1655-40.
