%0 Journal Article %T Change in Internal Energy and Enthalpy of Spinning Black Hole with Half Spin Parameter in XRBs %A Dipo Mahto %A Amresh Kumar Singh %A Niharika Kumari %J International Journal of Astronomy and Astrophysics %P 328-333 %@ 2161-4725 %D 2016 %I Scientific Research Publishing %R 10.4236/ijaa.2016.63027 %X Mahto et al. gave an expression for the change in enthalpy and internal energy with corresponding change in the radius of the event horizon of black holes of spin parameter a* = 1 (2013). On the basis of this research work, we have proposed an expression for the change in the internal energy and enthalpy of the spinning black holes to assume spin parameter a* = 1/2 and calculated their values for different test spinning black holes existing in XRBs. %K Enthalpy %K Spinning Black Holes %K Internal Energy %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=70745
