Gravastars with Dark Energy Evolving to Naked Singularity
R. Chan, M. F. A. da Silva, P. Senna +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…
Generalized AKNS System, Non-vanishing Boundary Conditions and N-Dark-Dark Solitons
A. de O. Assunção, H. Blas, M. J. B. F. da Silva
We consider certain boundary conditions supporting soliton solutions in the generalized non-linear Schrödinger equation (AKNS). Using the dressing transformation (DT) method and th…
Radiating Gravastars
R. Chan, M. F. A. da Silva, J. F. Villas da Rocha +1
Considering a Vaidya exterior spacetime, we study dynamical models of prototype gravastars, made of an infinitely thin spherical shell of a perfect fluid with the equation of state…
