Exact Kerr-like solution and its shadow in a gravity model with spontaneous Lorentz symmetry breaking
Chikun Ding, Changqing Liu, R. Casana +1
We obtain an exact Kerr-like black hole solution by solving the corresponding gravitational field equations in Einstein-bumblebee gravity model where Lorentz symmetry is spontaneou…

An exact Schwarzschild-like solution in a bumblebee gravity model
R. Casana, A. Cavalcante, F. P. Poulis +1
We have obtained an exact vacuum solution from a gravity sector contained in the minimal standard-model extension. The theoretical model assumes a Riemann spacetime coupled to the…
