(Dated: February 7, 2008) We study the gravitational collapse in (n+2)-D quasi-spherical Szekeres space-time (which possess no killing vectors) with dust as the matte...
متن کاملQuasi-spherical gravitational collapse and the role of initial data, anisotropy and inhomogeneity
Gravitational collapse is an important and challenging issue in Einstein gravity for the last two decades or more, particularly after the formation of famous singularity theorems [1] and Cosmic Censorship Conjecture (CCC) [2]. Moreover, the final outcome of gravitational collapse [3] in the background of general relativity is interesting both from the point of view of black hole physics as well...
متن کاملSome comments on the nature of initial data in spherical collapse
Various authors have shown the occurence of naked singularities and black holes in the spherical gravitational collapse of inhomogeneous dust. In a recent preprint, Antia has criticised a statement in a paper by Jhingan, Joshi and Singh on dust collapse. We show that his criticism is invalid. Antia shows that in Eulerian coordinates a series expansion for the density of a collapsing Newtonian f...
متن کاملRole of Pressure in Quasi-Spherical Gravitational Collapse
We study quasi-spherical Szekeres space-time (which possess no killing vectors) for perfect fluid, matter with tangential stress only and matter with anisotropic pressure respectively. In the first two cases cosmological solutions have been obtained and their asymptotic behaviour have been examined while for anisotropic pressure, gravitational collapse has been studied and the role of the press...
متن کاملOn the Role of Initial Data in Gravitational Collapse of Inhomogeneous Dust
We consider here the gravitational collapse of a spherically symmetric inhomogeneous dust cloud described by the Tolman-Bondi models. By studying a general class of these models, we find that the end state of the collapse is either a black hole or a naked singularity, depending on the parameters of the initial density distribution, which are ρc, the initial central density of the massive body, ...
