Einstein-Born-Infeld-dilaton black holes in non-asymptotically flat spacetimes

چکیده
We derive exact magnetically charged, static and spherically symmetric black hole solutions of the four-dimensional Einstein-Born-Infeld-dilaton gravity. These solutions are neither asymptotically flat nor (anti)-de Sitter. The properties of the solutions are discussed. It is shown that the black holes are stable against linear radial perturbations.

Non-supersymmetric Attractors in Born-Infeld Black Holes with a Cosmological Constant
We investigate the attractor mechanism for spherically symmetric extremal black holes in Einstein-Born-Infeld-dilaton theory of gravity in four-dimensions, in the presence of a cosmological constant. We look for solutions analytic near the horizon by using perturbation method. It is shown that the values of the scalar fields at the horizon are only dependent on the charges carried by the black ...
متن کاملSolitons and black holes in Einstein-Born-Infeld-dilaton theory
Static spherically symmetric asymptotically flat solutions to the U(1) BornInfeld theory coupled to gravity and to a dilaton are investigated. The dilaton enters in such a way that the theory is SL(2, R)symmetric for a unit value of the dilaton coupling constant. We find globally regular solutions for any value of the effective coupling which is the ratio of the gravitational and dilaton coupli...
متن کاملElectrically Charged Einstein-Born-Infeld Black Holes with Massive Dilaton
We numerically construct static and spherically symmetric electrically charged black hole solutions in Einstein-Born-Infeld gravity with massive dilaton. The numerical solutions show that the dilaton potential allows many more black hole causal structures than the massless dilaton. We find that depending on the black hole mass and charge and the dilaton mass the black holes can have either one,...
متن کاملBlack holes in three-dimensional Einstein-Born-Infeld-dilaton theory
The three-dimensional static and circularly symmetric solution of the Einstein-BornInfeld-dilaton system is derived. The solutions corresponding to low energy string theory are investigated in detail, which include black hole solutions if the cosmological constant is negative and the mass parameter exceeds a certain critical value. Some differences between the Born-Infeld nonlinear electrodynam...
متن کاملNon-asymptotically flat, non-dS/AdS dyonic black holes in dilaton gravity
We present exact spherically symmetric dyonic black hole solutions in fourdimensional and higher dimensional Einstein-Maxwell-dilaton gravity with Liouvilletype potentials for the dilaton field. These solutions have unusual asymptotics–they are neither asymptotically flat nor asymptotically (anti-) de Sitter. The solutions have one or two horizons hiding a curvature singularity at the origin. A...
