Change of Density when Chaplygin gas is accreting upon a black hole

TL;DR

This paper investigates how the density of modified Chaplygin gas changes during accretion and wind processes around a black hole, revealing high wind density near the black hole and a local density minimum associated with CENBOL.

Contribution

It provides the first detailed analysis of density variations of modified Chaplygin gas during black hole accretion and wind flows, identifying a local density minimum linked to CENBOL.

Findings

High wind density near the black hole

Low wind density far from the black hole

Presence of a local density minimum (CENBOL) during accretion

Abstract

In this work I study the density change along the accretion and wind branches when modified Chaplygin gas is taken to be the accreting fluid. I get a high wind density very near to black hole while a low wind density far from the black hole. In modified Chaplygin gas accretion case a local minima in accretion-density is got which can be detected as the CENBOL.
