Stability of Accretion Disc around a Black Hole: effects of Bremsstrahlung and Synchrotron Cooling
Sivakumar G. Manickam
We perform stability analysis of an accretion disc around a stellar mass black hole. The cooling of the accretion flow due to bremsstrahlung and synchrotron radiation processes are…
Parameter Dependence of Transonic Accretion onto a Black Hole in the Presence of Bremsstrahlung and Synchrotron Cooling
Sivakumar G. Manickam
The topologies are obtained for accretion flows around black holes as the parameters, accretion rate and specific angular momentum are varied. Paczy{ń}ski-Wiita pseudo-Newtonian po…
Accretion onto a Black Hole in the Presence of Bremsstrahlung Cooling - Parameter Space Study
Sivakumar G. Manickam, Sandip K. Chakrabarti
The dynamics of accretion onto a schwarzschild black hole is studied using Paczynski-Wiita pseudo newtonian potential. Steady state solution of the flow equations is obtained using…
Relation of Light Curve Behaviour with Accretion Rates in Black Hole Candidate GRS1915+105
Sandip K. Chakrabarti, A. Nandi, S. G. Manickam
We report some properties of the light curves of GRS 1915+105 and present their interpretation using the variation of net accretion rate.
Classification of Light curves of the Black Hole Candidate GRS1915+105
Anuj Nandi, Sivakumar G. Manickam, Sandip K. Chakrabarti
The black hole candidate GRS 1915+105 exhibits a rich variety of variability. Assuming that the earlier paradigm of black hole accretion which includes a shock is applicable for th…
