Emergent gravity from Michel flow with position dependent adiabatic index
Apashanka Das, Souvik Ghose, Tapas K. Das
Spherically symmetric, general relativistic Bondi accretion is known as the Michel flow. The stationary integral transonic solutions for the Michel flow has been constructed for mu…
On the spin dependence of the emergent gravity phenomena as observed in axially symmetric black hole accretion with spatially varying adiabatic index
Kalyanbrata Pal, Souvik Ghose, Ripon Sk +2
The present work addresses an axisymmetrically accreting black hole system from three perspectives: the astrophysical, the dynamical systems, and the emergent gravity standpoint. S…
Effect of spin on the dynamics of multi-component trans-relativistic accretion flows around Kerr black holes
Kalyanbrata Pal, Souvik Ghose, Shilpa Sarkar +1
We investigate the axially symmetric accretion of low angular momentum hydrodynamic matter onto a rotating black hole. The gravitational field under consideration is assumed to be…
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…
