Sources of matter for wormholes in a k-essence theory
Marcos V. de S. Silva, Carlos F. S. Pereira, Bruna Bragato +3
The paper investigates wormhole solutions in a k‑essence theory coupled to a phantom scalar field, deriving the scalar field, potential, and electromagnetic functions for electrica…
Three dimensional black bounces in gravity
Marcos V. de S. Silva, Manuel E. Rodrigues, C. F. S. Pereira
We investigate the existence of black bounce solutions in dimensions within the framework of gravity. We analyze whether black bounce geometries originally obtained in…
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…
Field Sources for Black-Bounce Solutions: The Case of K-Gravity
G. Alencar, M. Nilton, Manuel E. Rodrigues +1
In the framework of Simpson-Visser, the search for field sources that produce black-bounces in alternative gravity theories has remained unresolved. In this paper, the first in a s…
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…
Magnetically charged black-bounce solution via nonlinear electrodynamics in a k-essence theory
Carlos F. S. Pereira, Denis C. Rodrigues, Marcos V. de S. Silva +3
In the present work, we obtain and analyze a new class of analytical solutions of magnetically charged black bounces in k-essence theory, spherically symmetric in (3+1)-dimensions,…
