Relativistic sonic geometry for isothermal accretion in the Schwarzschild metric
Md Arif Shaikh, Ivleena Firdousi, Tapas K. Das
In this work, we perform linear perturbation on general relativistic isothermal accretion onto a non-rotating astrophysical black hole to study the salient features of the correspo…

Acoustic geometry obtained through the perturbation of the Bernoulli's constant
Satadal Datta, Md Arif Shaikh, Tapas K Das
For accretion onto astrophysical black holes, we demonstrate that linear perturbation of Bernoulli's constant defined for an inviscid irrotational adiabatic flow of perfect ideal f…
