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…
Fractals and the Distribution of Galaxies
Marcelo B. Ribeiro, Alexandre Y. Miguelote
This paper presents a review of the fractal approach for describing the large scale distribution of galaxies. We start by presenting a brief, but general, introduction to fractals,…
