Pseudo-Schwarzschild Spherical Accretion as a Classical Black Hole Analogue
Surajit Dasgupta, Neven Bilić, Tapas K. Das
We demonstrate that a spherical accretion onto astrophysical black holes, under the influence of Newtonian or various post-Newtonian pseudo-Schwarzschild gravitational potentials,…
Transonic Black Hole Accretion as Analogue System
Tapas Kumar Das
Classical black hole analogues (alternatively, the analogue systems) are fluid dynamical analogue of general relativistic black holes. Such analogue effects may be observed when ac…
Low angular momentum accretion-outflow model of flares from Sgr A
Tapas K. Das, Bozena Czerny
We employ a low angular momentum accretion-outflow scenario to model the flares emanating out from the central region of Sgr A. The primary donor for matter accreting onto the…
Analogous Hawking Radiation from Astrophysical Black Hole Accretion
Tapas Kumar Das
For the first time in literature, we provide an exact analytical scheme for calculating the analogous Hawking temperature and surface gravity for general relativistic accretion ont…
A simultaneous solution scheme for coupled transonic accretion-wind systems
Tapas Kumar Das
We discuss a {\it non-self-similar analytical model} capable of explaining the formation of accretion-powered galactic and extra-galactic jets.
On the Formation of Accretion-powered Galactic and Extra-galactic Outflows
Tapas Kumar Das
Though widely observed to be emanating from a variety of astrophysical sources, the underlying physical mechanism behind the formation of galactic and extragalactic outflows is sti…
