Adiabatic Anisotropic Gravitational Collapse in Painlevé-Gullstrand Coordinates: A Geometric Analysis
G. Abellán, N. Bolívar, A. Alexandrova +1
We present a detailed geometric analysis of adiabatic, anisotropic gravitational collapse formulated in a single Painlevé-Gullstrand coordinate system that covers both the interior…
Warp drive solutions in spherical coordinates with anisotropic matter configurations
Gabriel Abellán, Nelson Bolívar, Ivaylo Vasilev
In this work we study the influence of isotropic and anisotropic fluids on the spherically symmetric warp metric. We evaluate the energy conditions and the influence of including a…
Regularity condition on the anisotropy induced by gravitational decoupling in the framework of MGD
Gabriel Abellán, Victor Torres, Ernesto Fuenmayor +1
We use gravitational decoupling to establish a connection between the minimal geometric deformation approach and the standard method for obtaining anisotropic fluid solutions. Moti…
