Gravitational 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 کاملGravitational Collapse in Higher Dimension
Spherically symmetric inhomogeneous dust collapse has been studied in higher dimensional spacetime and appearance of naked singularity has been analyzed both for non-marginal and marginally bound cases. It has been shown that naked singularity is possible for any arbitrary dimension in non-marginally bound case. For marginally bound case we have examined the radial null geodesics from the singu...
متن کاملCritical Phenomena in Gravitational Collapse
It was well known that strong enough initial configurations of matter field would result in gravitational collapse to black holes, whereas weak enough initial data become dispersed to infinity. However, what happens in the intermediate region was not clear until the discovery of the critical phenomena in gravitational collapse by Choptuik in 1993 [1]. He examined numerically the spacetime evolu...
متن کاملCritical Phenomena in Gravitational Collapse
As first discovered by Choptuik, the black hole threshold in the space of initial data for general relativity shows both surprising structure and surprising simplicity. Universality, power-law scaling of the black hole mass, and scale echoing have given rise to the term "critical phenomena". They are explained by the existence of exact solutions which are attractors within the black hole thresh...
