Static spherical vacuum solutions in the bumblebee gravity model
نویسندگان
چکیده
The bumblebee gravity model is a vector-tensor theory of gravitation where the vector field nonminimally couples to Ricci tensor. By investigating vacuum equations with spherical symmetry, we find two families black-hole (BH) solutions in this model: one has vanishing radial component and other When coupling between tensor set zero, first family becomes Reissner-Nordstr\"om solution while second degenerates Schwarzschild being zero. General numerical both are obtained for nonzero Besides BH solutions, also reveal existence that have nonvanishing $tt$-component metric on supposed event horizon $rr$-component diverges curvature scalars finite. These not supported by existing observations but present certain properties academic interests. We conclude study putting into tests against Solar-system images supermassive BHs.

متن کاملSpherical Self-Similar Solutions in Einstein-Multi-Scalar Gravity
We consider a general non-linear sigma model coupled to Einstein gravity and show that in spherical symmetry and for a simple realization of self-similarity, the spacetime can be completely determined. We also examine some more specific matter models and discuss their relation to critical collapse. ∗Electronic Address: [email protected] †On leave from Departamento de F́ısica Teórica, U...

Classes of exact static solutions in four-dimensional Einstein-MaxwellDilaton gravity are found. Besides of the well-known solutions previously found in the literature, new solutions are presented.It’s shown that spherically symmetric solutions, except the case of charged dilaton black hole, represent globally naked strong curvature singularities. The scalar field is believed to play an importa...
متن کاملStatic spherically symmetric solutions for conformal gravity in three dimensions
Static spherically symmetric solutions for conformal gravity in three dimensions are found. Black holes and wormholes are included within this class. Asymptotically the black holes are spacetimes of arbitrary constant curvature, and they are conformally related to the matching of different solutions of constant curvature by means of an improper conformal transformation. The wormholes can be con...
متن کاملOn Static Solutions in 2D Dilaton Gravity with Scalar Matter
Within the first order formalism static solutions of generic dilaton gravity in 2D with self-interacting (scalar) matter can be discussed with ease. The question of (non)existence of Killing horizons is addressed and the interplay with asymptotic conditions is investigated. Naturally, such an analysis has to be a global one. A central element in the discussion is the rank of the Jacobi matrix o...
