Density profiles for Chaplygin gas accretion upon black holes: Moderately differentiated minima in wind branch
Department of Mathematics, Jadavpur University - Kolkata-700 032, India
Accepted: 26 September 2011
In this work we study the density change along the accretion and wind branches when a modified Chaplygin gas is taken to be the accreting fluid. We get a high wind density very near to the black hole whereas we get a low wind density far from the black hole. In the modified Chaplygin gas accretion case a local minimum in the accretion density is got which can be detected as the CENBOL.
