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…
Energy loss of a heavy quark produced in a finite-size quark-gluon plasma
P. B. Gossiaux, J. Aichelin, C. Brandt +2
We study the energy loss of an energetic heavy quark produced in a high temperature quark-gluon plasma and travelling a finite distance before emerging in the vacuum. While the ret…
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…
