Bondi Flow from Various Perspectives
Souvik Ghose, Tapas K. Das
Realization of the stationary integral solutions of steady state transonic accretion flow in spherical symmetry helps to understand accretion phenomena on various astrophysical obj…
Multi-criticality and related bifurcation in accretion discs around non-rotating black holes -- an analytical study
Arpan Krishna Mitra, Aishee Chakraborty, Pratik Tarafdar +1
Low angular momentum, general relativistic, axially symmetric accretion of hydrodynamic fluid onto Schwarzschild black holes may undergo more than one critical transition. To obtai…
Influence of flow thickness on general relativistic low angular momentum accretion around spinning black holes
Pratik Tarafdar, Susovan Maity, Tapas K. Das
General relativistic, axisymmetric flow of low angular momentum accretion around a Kerr black hole can have certain geometric configuration where the flow is maintained in hydrosta…
Dependence of acoustic surface gravity on disc thickness for accreting astrophysical black holes
Susovan Maity, Pratik Tarafdar, Md. Arif Shaikh +1
For axially symmetric accretion maintained in hydrostatic equilibrium along the vertical direction, we investigate how the characteristic features of the embedded acoustic geometry…
Effective sound speed in relativistic accretion discs around rotating black holes
Susovan Maity, Md Arif Shaikh, Tapas Kumar Das
For axially symmetric accretion maintained in the hydrostatic equilibrium along the vertical direction in the Kerr metric, the radial Mach number does not become unity at the criti…
Effective sound speed in relativistic accretion discs around Schwarzschild black holes
Md Arif Shaikh, Susovan Maity, Sankhasubhra Nag +1
For low angular momentum axially symmetric accretion flow maintained in hydrostatic equilibrium along the vertical direction, the value of the Mach number at the critical points de…
