Causal structure of singularity in non-spherical gravitational collapse

نویسندگان

چکیده

We investigate here the final state of gravitational collapse a non-spherical and non-marginally bound dust cloud as modeled by Szekeres spacetime. show that directionally globally naked singularity can be formed in this case near collapsing boundary, not at its geometric center is typically for spherical collapse. This strong curvature sense Tipler criterion on strength. The null geodesics escaping from would less scattered certain directions since close to boundary current scenario. physical implications are pointed out.

The Structure of Singularity in Gravitational Collapse

We will describe here the structure of singularity forming in gravitational collapse of spherically symmetric inhomogeneous dust. Such a collapse is described by the Tolman-Bondi-Lemâ itre metric. The main new result here relates, in a general way, the formation of black holes and naked shell-focusing singularities resulting as the final fate of such a collapse to the generic form of regular in...

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...

The 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...

Nonadiabatic Charged Spherical Gravitational Collapse

We present a complete set of the equations and matching conditions required for the description of physically meaningful charged, dissipative, spherically symmetric gravitational collapse with shear. Dissipation is described with both free-streaming and diffusion approximations. The effects of viscosity are also taken into account. The roles of different terms in the dynamical equation are anal...

Non-spherical gravitational collapse of strange quark matter

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...
