Viscous Transonic Accretion Flows in Kerr Black Hole Geometry
Abhrajit Bhattacharjee, Sandip K. Chakrabarti
We study viscous transonic accretion flows in vertical equilibrium in Kerr geometry. We employ the pseudo-Kerr formalism which accurately describes transonic flows around Kerr blac…

Effective potential approach to study hydrodynamics and particle dynamics in Kerr geometry
Abhrajit Bhattacharjee, Sandip K. Chakrabarti
We derive the exact form of effective potential in Kerr geometry from the general relativistic radial momentum equation. The effective potential accurately mimics the general relat…
