Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
In this work, we analyze some matter sources associated with wormhole models within a k-essence theory coupled to the gravitational sector through a phantom scalar field. We adopt…
Black-bounce solutions in a k-essence theory under the effects of bumblebee gravity
Carlos F. S. Pereira, Marcos V. de S. Silva, H. Belich +3
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 configurat…
Spherically symmetric and static black bounces with multiple horizons, throats, and anti-throats in four dimensions
Manuel E. Rodrigues, Marcos V. de S. Silva
Black bounce spacetimes usually arise from the Simpson-Visser regularization method. This type of metric presents a wormhole throat inside an event horizon. In this paper, we prese…
Generalized black-bounces solutions in f(R) gravity and their field sources
Marcos V. de S. Silva, T. M. Crispim, G. Alencar +2
In this work, following our recent findings in [1], we extend our analysis to explore the generalization of spherically symmetric and static black-bounce solutions, known from Gene…
