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

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.
