GRAVITYSURFACE propertiesSURFACE analysisBLACK holesWe analyze the properties of the black hole surface gravity by using an alternative approach based upon the use of light surfaces that are represented by certain characteristic frequencies. To this end, we rewrite the Kerr line element in terms o...

For a black hole family solution the surface charge conservationimplies the f i rst law of black hole mechanics. As a check we show the f i rst law for blackhole electrically charged, rotating, and with an asymptotically constant curvature (the Kerr-Newman (anti-)de Sitter family). The ...
We analyze the properties of the black hole surface gravity by using an alternative approach based upon the use of light surfaces that are represented by certain characteristic frequencies. To this end, we rewrite the Kerr line element in terms of the characteristic frequencies, which allows us ...
We construct the marginal loosely trapped surface (marginal LTS) for the Kerr spacetime with a small Kerr parameter perturbatively, where the LTS condition is saturated. An LTS is a surface that specifies the strong gravity region, which is a generalization of the photon sphere in the ...

BLACK holesWe evaluate the surface energy ( E s ± ), rotational energy ( E r ± ) and electromagnetic energy ( E em ± ) for a Kerr-Sen black hole (BH) having the event horizon ( H ) and the Cauchy horizon ( H - ). Interestingly, we find that the sum of these three ...
