Global Transonic Solution of magnetized dissipative accretion flow around non-rotating black holes with thermal conduction

Abstract

Our goal is to obtain a set of global transonic accretion solutions for magnetized dissipative accretion flows around non-rotating black holes. To achieve this, we have considered a steady state, axisymmetric, and viscous advection-dominated accretion disc. Additionally, we have investigated the effects of thermal conduction and bremsstrahlung cooling on hot accretion flow. We also have examined the properties of the dynamical variables of the flow in their presence. We have found that the nature of transonic solutions is modified by changing the thermal conduction parameter and cooling factor. We have determined the critical values of the thermal conduction and cooling parameters that provide the global accretion solutions. Furthermore, we have estimated the disc’s luminosity in our model and have applied it to Sgr A${}^{\ast }$
