A perfect fluid model for compact stars
Gabino Estevez Delgado, Joaquin Estevez Delgado, Nadiezhda Montelongo Garcia +1
In the framework of Einstein's the theory of general relativity we present a new interior solution with a perfect fluid, this is constructed from the proposal of a gravitational re…
Kerr-Like Phantom Wormhole
Galaxia Miranda, Tonatiuh Matos, Nadiezhda Motelongo García
In this work we study a Kerr-like wormhole with phantom matter as source. It has three parameters: mass, angular momentum and scalar field charge. This wormhole has a naked ring si…
Linearised stability analysis of generic thin shells
Francisco S. N. Lobo, Prado Martin-Moruno, Nadiezhda Montelongo Garcia +1
We construct generic spherically symmetric thin shells by using the cut-and-paste procedure. We take considerable effort to make the analysis as general and unified as practicable;…
Generic thin-shell gravastars
Prado Martin-Moruno, Nadiezhda Montelongo Garcia, Francisco S. N. Lobo +1
We construct generic spherically symmetric thin-shell gravastars by using the cut-and-paste procedure. We take considerable effort to make the analysis as general and unified as pr…
Generic spherically symmetric dynamic thin-shell traversable wormholes in standard general relativity
Nadiezhda Montelongo Garcia, Francisco S. N. Lobo, Matt Visser
We consider the construction of generic spherically symmetric thin-shell traversable wormhole spacetimes in standard general relativity. By using the cut-and-paste procedure, we co…
Exact solutions of Brans-Dicke wormholes in the presence of matter
Nadiezhda Montelongo Garcia, Francisco S. N. Lobo
A fundamental ingredient in wormhole physics is the presence of exotic matter, which involves the violation of the null energy condition. Although a plethora of wormhole solutions…
Nonminimal curvature-matter coupled wormholes with matter satisfying the null energy condition
Nadiezhda Montelongo Garcia, Francisco S. N. Lobo
Recently, exact solutions of wormhole geometries supported by a nonminimal curvature-matter coupling were found, where the nonminimal coupling minimizes the violation of the null e…
Wormhole geometries supported by a nonminimal curvature-matter coupling
Nadiezhda Montelongo Garcia, Francisco S. N. Lobo
Wormhole geometries in curvature-matter coupled modified gravity are explored, by considering an explicit nonminimal coupling between an arbitrary function of the scalar curvature,…
On the Structure of the Effective Potential for a Spherical Wormhole
N. Montelongo Garcia, T. Zannias
The structure of the effective potential describing causal geodesics near the throat of an arbitrary spherical wormhole is analyzed. Einstein's equations relative to a set of r…
