Bounded excursion stable gravastars and black holes
P. Rocha, A. Y. Miguelote, R. Chan +3
Dynamical models of prototype gravastars were constructed in order to study their stability. The models are the Visser-Wiltshire three-layer gravastars, in which an infinitely thin…
Gravitational Collapse of Circularly Symmetric Stiff Fluid with Self-Similarity in 2+1 Gravity
A. Y. Miguelote, N. A. Tomimura, Anzhong Wang
Linear perturbations of homothetic self-similar stiff fluid solutions, , with circular symmetry in 2+1 gravity are studied. It is found that, except for those with an…
Gravitational Collapse of Self-Similar Perfect Fluid in 2+1 Gravity
A. Y. Miguelote, N. A. Tomimura, Anzhong Wang
Perfect fluid with kinematic self-similarity is studied in 2+1 dimensional spacetimes with circular symmetry, and various exact solutions to the Einstein field equations are given.…
Levi-Civita Solutions Coupled with Electromagnetic Fields
A. Y. Miguelote, M. F. A. da Silva, A. Z. Wang +1
The local and global properties of the Levi-Civita (LC) solutions coupled with an electromagnetic field are studied and some limits to the vacuum LC solutions are given. By doing s…
