A quasi-black hole, either nonextremal or extremal, can be broadly defined as the limiting configuration of a body when its boundary approaches the body's quasihorizon. We consider the mass contributions and the mass formula for a static quasi-black hole. The analysis involves careful scrutiny ...
horizon radii product, entropy product, and irreducible mass product of the event horizon and Cauchy horizon are universal, the surface gravity product, the surface temperature product and the Komar energy product of the said horizons do not seem to be universal for Kerr–Newman black hole spaceti...
black hole physics, galaxies: nuclei, gravitational wavesAlthough the gravitational wave kick velocity in the orbital plane of coalescing black holes has been understood for some time, apparently conflicting formulae have been proposed for the dominant out-of-plane kick, each a good fit to ...
The microscopic formula for the degeneracies of 1/8 BPS black holes in type II string theory compactified on a six dimensional torus can be expressed as a sum of several terms. One of the terms is a function of the Cremmer-Julia invariant and gives the leading contribution to the entropy...

The Isolated Horizon formalism, together with a simple phenomenological modelfor colored black holes was recently used to predict a formula for the ADM massof the solitons of the EYM system in terms of horizon properties of black holes{\it for all} values of the horizon area. In this note,...
Black holes in the Brans-Dicke theory of gravitation It is shown that a stationary space containing a black hole is a solution of the Brans-Dicke field equations if and only if it is a solution of the Einstei... SW Hawking - 《Communications in Mathematical Physics》 被引量: 240发表: ...
