Advective accretion flow properties around rotating black holes a?? application to GRO J1655-40

摘要

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 ($lpha$). Further, we carry out the model calculation of quasi-periodic oscillation frequency ($u_{m QPO}$) that is frequentlyobserved in black hole sources and observe that $u^{max}_{m QPO}$ increases with the increase of black hole spin ($a_{m k}$). Then, we employ our model in order to explain the High Frequency Quasi-Periodic Oscillations (HFQPOs) observedin black hole source GROJ1655-40. While doing this, we attempt to constrain the range of $a_k$ based on observed HFQPOs ($sim$300 Hz and $sim$450 Hz) for the black hole source GRO J1655-40.
