On Uniformly Accelerated Black Holes
The static and stationary C-metric are revisited in a generic framework and their interpretations studied in some detail. Specially those with two event horizons, one for the black hole and another for the acceleration. We found that: i) The spacetime of an accelerated static black hole is plagued by either conical singularities or lack of smoothness and compactness of the black hole horizon; i...
متن کاملBlack Holes in Accelerated Universe
We have analyzed the evolution of mass of a stationary black hole in the standard FRW cosmological model. The evolution is determined specifically about the time of transition from the earlier matter to the later exotic dark energy dominated universe. It turns out that the accretion rate of matter on the black hole of mass M was approximately 10M higher than the accretion rate of exotic dark en...
متن کاملBlack holes surrounded by uniformly rotating rings
Black Holes have grown to become a well accepted member of the canon of astrophysical objects. Nonetheless, there is still very little known about spacetimes containing both matter and Black Holes. But for a few exceptions (e.g. the Oppenheimer-Snyder collapse), such situations have been considered using approximation methods, perturbation techniques or pioneering, but still somewhat inaccurate...
متن کاملQuantum stability of accelerated black holes.
We study quantum aspects of the accelerated black holes in some detail. Explicitly shown is the fact that a uniform acceleration stabilizes certain charged black holes against the well-known thermal evaporation. Furthermore, a close inspection of the geometry reveals that this is possible only for near-extremal black holes and that most nonextremal varieties continue to evaporate with a modifie...
متن کاملUniformly accelerating black holes in a de Sitter universe
A class of exact solutions of Einstein’s equations is analysed which describes uniformly accelerating charged black holes in an asymptotically de Sitter universe. This is a generalisation of the C-metric which includes a cosmological constant. The physical interpretation of the solutions is facilitated by the introduction of a new coordinate system for de Sitter space which is adapted to accele...
