Accretion disks around a static black hole in gravity
Saheb Soroushfar, Sudhaker Upadhyay
We provide a description of a thin accretion disc for a static spherically symmetric black holes in gravity. In this regard, we first study the horizons of black holes in $f…

Phase transition of a charged AdS black hole with a global monopole through geometrical thermodynamics
Saheb Soroushfar, Sudhaker Upadhyay
In order to study the phase transition through thermodynamic geometry, we consider the charged AdS black hole with global monopole. We first introduce thermodynamics of charged AdS…

Thermodynamic geometry of a black hole surrounded by perfect fluid in Rastall theory
Saheb Soroushfar, Reza Saffari, Sudhaker Upadhyay
In this paper, we study thermodynamics and thermodynamic geometry of a black hole surrounded by the perfect fluid in Rastall theory. In particular, we calculate the physical quanti…
