Black-bounce solutions in a k-essence theory under the effects of bumblebee gravity
Abstract
In the present study, we analyze the effects of violation of Lorentz symmetry for black-bounce solutions in a -essence theory that has the form of a power law for the configuration . We perform such analysis for a known model explored in previous work and complement the proposal with a new black-bounce model for the area functions . This model has the Schwarzschild-de Sitter asymptomatic behavior for , and we investigate the scalar field, potential, and energy conditions for both models. We have shown that the violation of Lorentz symmetry can be generated through -essence without the need for an additional field. These results corroborate the validation of other previously investigated wormhole solutions.
