Gravitational collapse and formation of universal horizons
Miao Tian, Xinwen Wang, M. F. da Silva +1
In this paper, we first generalize the definition of stationary universal horizons to dynamical ones, and then show that (dynamical) universal horizons can be formed from realistic…
How the Charge Can Affect the Formation of Gravastars
R. Chan, M. F. A. da Silva
In recent work we physically interpreted a special gravastar solution characterized by a zero Schwarzschild mass. In fact, in that case, none gravastar was formed and the shell exp…
Dynamical Evolution of an Unstable Gravastar with Zero Mass
R. Chan, M. F. A. da Silva, Jaime F. Villas da Rocha
Using the conventional gravastar model, that is, an object constituted by two components where one of them is a massive infinitely thin shell and the other one is a de Sitter inter…
How the Cosmological Constant Affects Gravastar Formation
R. Chan, M. F. A. da Silva, P. Rocha
Here we generalized a previous model of gravastar consisted of an internal de Sitter spacetime, a dynamical infinitely thin shell with an equation of state, but now we consider an…
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…
Star Models with Dark Energy
R. Chan, M. F. A. da Silva, J. F. Villas da Rocha
We have constructed star models consisting of four parts: (i) a homogeneous inner core with anisotropic pressure (ii) an infinitesimal thin shell separating the core and the envelo…
