Gravitational Collapse of an Imperfect Non Adiabatic Fluid
R. Chan, M. F. A. da Silva, C. F. C. Brandt
We study the evolution of an anisotropic shear-free fluid with heat flux and kinematic self-similarity of the second kind. We found a class of solution to the Einstein field equati…
Charged Gravastar in a Dark Energy Universe
C. F. C. Brandt, R. Chan, M. F. A. da Silva +1
Here we constructed a charged gravastar model formed by an interior de Sitter spacetime, a charged dynamical infinitely thin shell with an equation of state and an exterior de Sitt…
Gravastars with an Interior Dark Energy Fluid Forming a Naked Singularity
C. F. C. Brandt, R. Chan, M. F. A. da Silva +1
We consider a gravastar model made of anisotropic dark energy with an infinitely thin spherical shell of a perfect fluid with the equation of state with an external de…
Dressing a Naked Singularity: an Example
C. F. C. Brandt, R. Chan, M. F. A. da Silva +1
Considering the evolution of a perfect fluid with self-similarity of the second kind, we have found that an initial naked singularity can be trapped by an event horizon due to coll…
Gravitational collapse of spherically symmetric perfect fluid with kinematic self-similarity
C. F. C. Brandt, L. -M. Lin, J. F. Villas da Rocha +1
Analytic spherically symmetric solutions of the Einstein field equations coupled with a perfect fluid and with self-similarities of the zeroth, first and second kinds, found recent…
