Energy of Spinning Black Holes in XRBs and AGN

Dipo Mahto, Md Shams Nadeem, Umakant Prasad and Kumari Vineeta

Aims: To justify the model for energy of spinning black holes (E_BHS = K_BHS R_S) where K_BHS is the black hole constant having the value 1.214×10⁴⁴ Jm^-1 as proposed Dipo Mahto et al. (2011).

Study Design: Data for the mass of black holes have collected from the research paper entitled :Super massive Black Holes in Galactic Nuclei: Past Present and Future Research(2005), Space Science Reviews by L. Ferrarese and H. Ford and Black holes in Astrophysics (2005), New Journal Physics by R. Narayan. The data for the energy of black holes are taken from the paper entitled: The nature of the energy source in radio galaxies and active galactic nuclei, International Astronomical Union (1982) by V. Pacini and M. Salvati and acceleration and radiation processes around active galactic nuclei, Astrophysics and Space Science (1985) by V. Krishan.

Place and Duration of Study: Department of Physics, Marwari College Bhagalpur and University Department of Physics, T.M.B.U. Bhagalpur, between October 2013 and February 2014.

Methodology: A theoretical based work using Laptop to calculate the calculation for energy of spinning black holes at Marwari College Bhagalpur and the residential research chamber of the first author.

Results: The calculation shows that the total energy of the rest masses for stellar-mass black holes (M ~ 5-20 M_θ) in X-ray binaries is few×10⁵⁵ ergs and for the super massive black holes (M ~ 10⁶-10^9.5 M_θ) in active galactic nuclei is few×10⁶⁰-10⁶⁴ergs.

Our result agrees with the result of other research work done previously by Pacini and Salvati and by Krishan and justifies the validity of this model.

Conclusion: The validity of model (E_BHS = K_BHS R_S) is justified which agrees with the result of other research work done earlier by Pacini and Salvati (1982) and Krishan (1985).
