Properties of Accretion Shocks in Viscous Flows with Cooling Effects
Santabrata Das, Sandip K. Chakrabarti
Low angular momentum accretion flows can have standing and oscillating shock waves. We study the region of the parameter space in which multiple sonic points occur in viscous flows…
Properties of Accretion Shock Waves in Viscous Flows Around Black Holes
Sandip K. Chakrabarti, Santabrata Das
Accretion flows having low angular momentum and low viscosity can have standing shock waves. These shocks arise due to the presence of multiple sonic points in the flow. We study t…
Computation of outflow rates from accretion disks around black holes
Santabrata Das, Indranil Chattopadhyay, A. Nandi +1
We self-consistently estimate the outflow rate from the accretion rates of an accretion disk around a black hole in which both the Keplerian and the sub-Keplerian matter flows simu…
Model Dependence of Transonic Properties of Accretion Flows Around Black Holes
S. K. Chakrabarti, Santabrata Das
We analytically study how the behaviour of accretion flows changes when the flow model is varied. We study the transonic properties of the conical flow, a flow of constant height a…
Radiatively driven electron-positron jets from two component accretion flows
Indranil Chattopadhyay, Santabrata Das, Sandip K. Chakrabarti
Matter accreting onto black holes has long been known to have standing or oscillating shock waves. The post-shock matter puffs up in the form of a torus, which intercepts soft phot…
