متن کاملEvaporation and fate of dilatonic black holes.
We study both spherically symmetric and rotating black holes with dilaton coupling, and discuss the evaporation of these black holes via Hawking’s quantum radiation and their fates. We find that the dilaton coupling constant α drastically affects the emission rates, and therefore the fates of the black holes. When the charge is conserved, the emission rate from the non-rotating hole is drastica...
متن کامل4D and 2D Evaporating Dilatonic Black Holes
The picture of S-wave scattering from a 4D extremal dilatonic black hole is examined. Classically, a small matter shock wave will form a non-extremal black hole. In the “throat region” the r − t geometry is exactly that of a collapsing 2D black hole. The 4D Hawking radiation (in this classical background) gives the 2D Hawking radiation exactly in the throat region. Inclusion of the back-reactio...
متن کاملVortices and black holes in dilatonic gravity
The extrapolation of the black hole ‘no-hair’ conjecture, initially proposed by Ruffini and Wheeler [1] and stating that a stationary black hole is uniquely determined by its mass, electromagnetic charge and angular momentum, to the stronger statement of ‘no dressing’ of the horizon, has been proven to be false [2], [3]. A common feature of such ‘counterexamples’ is that they involve nontrivial...
متن کاملDilatonic monopoles and ”hairy” black holes
We study gravitating monopoles and non-abelian black holes of SU(2) EinsteinYang-Mills-Higgs theory coupled to a massless dilaton. The domain of existence of these solutions is bounded and decreases with increasing dilaton coupling strength. The critical solutions of this system are Einstein-Maxwell-dilaton solutions.
