Dimensional dependence of naked singularity formation in spherical gravitational collapse
The complete spectrum of the endstates naked singularities, or blackholes of gravitational collapse is analyzed for a wide class of N -dimensional spacetimes in spherical symmetry, which includes and generalizes the dust solutions and the case of vanishing radial stresses. The final fate of the collapse is shown to be fully determined by the local behavior of a single scalar function and by the...
متن کاملThe Nature of Central Singularity in Spherical Dust Collapse
We examine here the nature of the central singularity forming in the spherically symmetric collapse of a dust cloud and it is shown that this is always a strong curvature singularity where gravitational tidal forces diverge powerfully. An important consequence is that the nature of the naked singularity forming in the dust collapse turns out to be stable against the perturbations in the initial...
متن کاملThe Structure of Singularity in Spherical Inhomogeneous Dust Collapse
We study here the structure of singularity forming in gravitational collapse of spherically symmetric inhomogeneous dust. Such a collapse is described by the TolmanBondi-Lemâitre metric, which is a two-parameter family of solutions to Einstein equations, characterized by two free functions of the radial coordinate, namely the ‘mass function’ F (r) and the ‘energy function’ f(r). The main new re...
متن کاملNaked singularity formation for higher dimensional inhomogeneous dust collapse
The Cosmic Censorship Conjecture (CCC)[1,2] states that the space-time singularity produced by gravitational collapse must be covered by the horizon. The CCC is yet one of the unresolved problem in General Relativity. In fact the conjecture has not yet any precise mathematical proof. However the singularity theorems as such do not state anything about the visibility of the singularity to an out...
متن کاملKUNS 1500 Naked singularity formation in the collapse of a spherical cloud of counterrotating particles
We investigate collapse of a spherical cloud of counter-rotating particles. An explicit solution is given using an elliptic integral. If the speci c angular momentum L(r) = O(r) at r! 0, no central singularity occurs. With L(r) like that, there is a nite region around the center that bounces. On the other hand, if the order of L(r) is higher than that, a central singularity occurs. In marginall...
