Gravitational Collapse with Non–vanishing Tangential Stresses Ii: Extension to the Charged Case and General Solution
The exact solutions of the Einstein field equations describing spherically symmetric, ani-sotropic elastic spheres supported only by tangential stresses are generalized to the case of materials carrying a non–vanishing charge density. Using the mass–area system of coordinates first proposed by Ori for dust models, the general solution is then reduced to a very simple form in which only an integ...
متن کاملGravitational Collapse with Non–vanishing Tangential Stresses Ii: a Laboratory for Cosmic Censorship Experiments
The general exact solution describing the dynamics of anisotropic elastic spheres supported only by tangential stresses is reduced to a quadrature using Ori’s mass–area coordinates. This leads to the explicit construction of the root equation governing the nature of the central singularity. Using this equation, we formulate and motivate on physical grounds a conjecture on the nature of this sin...
متن کاملGravitational Collapse
We review here some recent developments on the issue of final fate of gravitational collapse within the framework of Einstein theory of gravity. The structure of collapsed object is discussed in terms of either a black hole or a singularity having causal connection with outside universe. Implications for cosmic censorship are discussed.
متن کاملGravitational Waves from Gravitational Collapse
Gravitational wave emission from stellar collapse has been studied for more than three decades. Current state-of-the-art numerical investigations of collapse include those that use progenitors with more realistic angular momentum profiles, properly treat microphysics issues, account for general relativity, and examine non-axisymmetric effects in three dimensions. Such simulations predict that g...
متن کاملNegative Pressure and Naked Singularities in Spherical Gravitational Collapse
Assuming the weak energy condition, we study the nature of the non-central shell-focussing singularity which can form in the gravitational collapse of a spherical compact object in classical general relativity. We show that if the radial pressure is positive, the singularity is covered by a horizon. For negative radial pressures, the singularity will be covered if the ratio of pressure to the d...
