Non-Spherical Gravitational Collapse of Strange Quark Matter

Abstract

We study the non-spherical gravitational collapse of the strange quark null fluid. The interesting feature which emerges is that the non-spherical collapse of charged strange quark matter leads to a naked singularity whereas the gravitational collapse of neutral quark matter proceeds to form a black hole. In the present brief report we extend the earlier work of T.Harko and K.S.Cheng to the non-spherical case.

A Cylindrically Symmetric and Static Anisotropic Fluid Spacetime and the Naked Singularity

“…Therefore, gravitational collapse in cylindrical symmetric system is the simplest one which contains both collapsing body and gravitational waves. A small samples of gravitational collapse model in this system with naked singularities are [5,6,7,8,9,10,11,12,13,14,15,16,17,18]. Some other nonspherical gravitational collapse model also possesses a naked singularity (e.g.…”

Scalar field pressure in induced gravity with Higgs potential and dark matter

“…Actually, the Cosmic Censorship Conjecture (CCC) [39] prohibits such singularities, which are widely regarded as nonexistent. However, their appearance is theoretically predicted in several models of gravity [40][41][42][43][44][45]. Different classes of BH and wormhole solutions as well as the nonsingular spherically symmetric solution in such models have been constructed and analysed in different contexts [46][47][48][49][50].…”

Dynamics of Apparent Horizons in ( N + 2)-Dimensional Space-Times

“…These include dust, [1,2] radiation [3,4] and null strange quark fluid. [5,6] Solutions to the Einstein equations in higher dimensions have come to play an important role in general relativity. Recently there has been a great deal of interest in models wherein the size of the extra dimensions is much larger than the Planck length.…”
