2+1-dimensional black holes with momentum and angular momentum
Exact solutions of Einstein’s equations in 2+1-dimensional anti-de Sitter space containing any number of black holes are described. In addition to the black holes these spacetimes can possess “internal” structure. Accordingly the generic spacetime of this type depends on a large number of parameters. Half of these can be taken as mass parameters, and the rest as the conjugate (angular) momenta....
متن کاملAngular momentum and the formation of stars and black holes
The formation of compact objects like stars and black holes is strongly constrained by the requirement that nearly all of the initial angular momentum of the diffuse material from which they form must be removed or redistributed during their formation. The processes likely to be involved and their implications are discussed for (1) low-mass stars, which may typically form in binary or multiple ...
متن کاملEnergy and Angular Momentum of Dilaton Black Holes
Abstract Following a prior paper, we review the results for the energy and angular momentum of a KerrNewman black hole, and then calculate the same properties for the case of a generalised rotating dilaton of the type derived, without rotation, by Garfinkle, Horowitz, and Strominger (1991; 1992). We show that there is, as far as it refers only to the energy and angular momentum, an interaction ...
متن کاملAbsorption of angular momentum by black holes and D-branes
We consider the absorption of higher angular momentum modes of scalars into black holes, at low energies, and ask if the resulting cross sections are reproduced by a D-brane model. To get the correct dependence on the volume of the compactified dimensions, we must let the absorbing element in the brane model have a tension that is the geometric mean of the tensions of the D-string and an effect...
متن کاملBlack hole mass and angular momentum in 2+1 gravity
We propose a new definition for the mass and angular momentum of neutral or electrically charged black holes in 2+1 gravity with two Killing vectors. These finite conserved quantities, associated with the SL(2, R) invariance of the reduced mechanical system, are shown to be identical to the quasilocal conserved quantities for an improved gravitational action corresponding to mixed boundary cond...
