Simple Analytic Models of Gravitational Collapse
Black holes and singularities are certainly some of the most peculiar and interesting features of general relativity[1]. From the perspective of fundamental theory their properties are far from completely understood, especially their relation to quantum theory[2]; from the perspective of astrophysics and observational astronomy they seem more and more to play a central role in the physics of ob...
متن کاملA Simple Model of Dimensional Collapse
We consider a simple model of d families of scalar field interacting with geometry in two dimensions. The geometry is locally flat and has only global degrees of freedom. When d < 0 the universe is locally two dimensional but for d > 0 it collapses to a one dimensional manifold. The model has some, but not all, of the characteristics believed to be features of the full theory of conformal matte...
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...
