Stability of a vacuum nonsingular black hole
This is the first of series of papers in which we investigate stability of the spherically symmetric space-time with de Sitter center. Geometry, asymptotically Schwarzschild for large r and asymptotically de Sitter as r → 0, describes a vacuum nonsingular black hole for m ≥ mcr and particle-like self-gravitating structure for m < mcr where a critical value mcr depends on the scale of the symmet...
متن کاملNonsingular black hole evaporation and "stable" remnants.
We examine the evaporation of two–dimensional black holes, the classical space–times of which are extended geometries, like for example the two–dimensional section of the extremal Reissner–Nordstrom black hole. We find that the evaporation in two particular models proceeds to a stable end–point. This should represent the generic behavior of a certain class of two–dimensional dilaton–gravity mod...

متن کاملEnergy associated with a static spherically symmetric nonsingular black hole
We evaluate the energy distributions of the Dymnikova space-time using the Weinberg, Papapetrou, and Møller energy-momentum complexes. This result sustain the importance of the energy-momentum complexes in the evaluation of the energy distribution of a given space-time. To compare the energy distributions obtained by using several definitions, these results show that the Einstein, Tolman, and W...
متن کاملSpinning Particle, Rotating Black Hole and Twistor-string * Rotating Black Hole as Spinning Particle
Structure of the spinning particle based on the rotating black hole solution is considered. It has gyromagnetic ratio g = 2 and a nontriv-ial twistorial and stringy systems. The mass and spin appear from excitations of the Kerr circular string, while the Dirac equation describes excitations of an axial stringy system which is responsible for scattering. Complex Kerr geometry contains an open tw...
