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…

Radiating Gravitational Collapse with Shearing Motion and Bulk Viscosity Revisited
G. Pinheiro, R. Chan
A new model is proposed to a collapsing star consisting of an anisotropic fluid with bulk viscosity, radial heat flow and outgoing radiation. In a previous paper one of us has intr…
