A Study on Mathematical Model of Entropy Change of Bosonic Field of Black Holes of Spin Parameters (a*= +3, -3) in XRBs and AGN

Abstract

The present work is concerned to discuss a model for the change in entropy of spinning black holes w.r.t. the mass(Mahto and Kumari 2018 & Mahto et al. 2020) of spin parameters a* = +3 & -3  and concludes that the bosonic field of black holes of co-rotation decreases the entropy and the same of black holes of counter rotation increases the entropy. The present model also predicts the emission of energy due to loss of mass in the form of Hawking radiation and dark matter and energy.
