Dynamical instability for radiating anisotropic collapse
R. Chan,L. Herrera,N. O. Santos +2 more
TL;DR: In this article, the role of local anisotropy and radiation in the onset of dynamical instabilities in free-streaming regime was investigated. But the role played by local anotropy was not investigated.
Journal ArticleDOI
Nonadiabatic charged spherical gravitational collapse
TL;DR: In this paper, a complete set of the equations and matching conditions required for the description of physically meaningful charged, dissipative, spherically symmetric gravitational collapse with shear is presented.
Journal ArticleDOI
Dynamical Instability for Shearing Viscous Collapse
R. Chan,L. Herrera,N. O. Santos +2 more
TL;DR: In this article, the role played by the shear and the shearing viscosity in the onset of dynamical instabilities was studied. And the role of shear in the stability of the system was investigated in both the Newtonian and relativistic regimes.
Journal ArticleDOI
The Levi–Civita space–time
TL;DR: In this paper, two exact solutions of Einstein's field equations corresponding to a cylinder of dust with net zero angular momentum are considered and the junction conditions to the exterior static vacuum Levi-Civita space time are studied.
