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…
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…
