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…
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,…
Generalized models for black-bounce solutions in Gravity
Júlio C. Fabris, Ednaldo L. B. Junior, Manuel E. Rodrigues
In this article, the implementation of black-bounce solutions in theories is investigated. Black-bounce solutions are regular configurations of the static spherically symmet…
Black-bounce solution in -essence theories
Carlos F. S. Pereira, Denis C. Rodrigues, Júlio C. Fabris +1
In the present work, we construct black-bounce configurations in the context of -essence theory. The solutions have a regular metric function at the origin. The area metric func…
