Critical properties of spherically symmetric accretion in a fractal medium
Nirupam Roy, Arnab K. Ray
Spherically symmetric transonic accretion of a fractal medium has been studied in both the stationary and the dynamic regimes. The stationary transonic solution is greatly sensitiv…
Static and dynamic aspects of transonicity in Bondi accretion
Arnab K. Ray, Jayanta K. Bhattacharjee
Transonicity in a spherically symmetric accreting system has been considered in both the stationary and the dynamic regimes. The stationary flow, set up as a dynamical system, has…
Axisymmetric black hole accretion in the Kerr metric as an autonomous dynamical system
Sanghamitra Goswami, Saba Nashreen Khan, Arnab K. Ray +1
In a stationary, general relativistic, axisymmetric, inviscid and rotational accretion flow, described within the Kerr geometric framework, transonicity has been examined by settin…
Critical properties of spherically symmetric black hole accretion in Schwarzschild geometry
Ipsita Mandal, Arnab K. Ray, Tapas Kumar Das
The stationary spherically symmetric accretion flow in the Schwarzschild metric has been set up as an autonomous first-order dynamical system, and it has been studied completely an…
