Gravitationally Collapsing Shells in (2+1) Dimensions
We study gravitationally collapsing models of pressureless dust, fluids with pressure, and the generalized Chaplygin gas (GCG) shell in (2+1)-dimensional spacetimes. Various collapse scenarios are investigated under a variety of the background configurations such as anti-de Sitter(AdS) black hole, de Sitter (dS) space, flat and AdS space with a conical deficit. As with the case of a disk of dus...
متن کاملNoncommutative Black Holes from Gravitationally Collapsing Shells
We study the formation of the (noncommutative) Schwarzschild black hole from collapsing polytropic and Chaplygin gas shells. We show that the collapsing shell forms either a black hole or a naked singular shell with the help of the pressure. A slight modification of collapsing shell that consists of the smeared gravitational sources can form a noncommutative Schwarzschild black hole while this ...
متن کاملCollapsing Shells and the Isoperimetric Inequality for Black Holes
Recent results of Trudinger on Isoperimetric Inequalities for non-convex bodies are applied to the gravitational collapse of a lightlike shell of matter to form a black hole. Using some integral identities for co-dimension two surfaces in Minkowski spacetime, the area A of the apparent horizon is shown to be bounded above in terms of the mass M by the 16πG 2 M 2 , which is consistent with the C...
متن کاملCollapsing Shells of Radiation in Higher Dimensional Spacetime and Cosmic Censorship Conjecture
Gravitational collapse of radiation shells in a non self-similar higher dimensional spherically symmetric spacetime is studied. Strong curvature naked singularities form for a highly inhomogeneous collapse, violating the cosmic censorship conjecture. As a special case, self similar models can be constructed.
متن کاملThe exact dynamical solution for two dust shells collapsing towards a black hole
The gravitational collapse of a star is an important issue both for general relativity and astrophysics, which is related to the well known “frozen star" paradox. Following the seminal work of Oppenheimer and Schneider (1939), we present the exact solution for two dust shells collapsing towards a pre-existing black hole. We find that the inner region of the shell is influenced by the property o...
