Gravitational Dust Collapse with Cosmological Constant
نویسنده
چکیده
In this paper, we study the effect of a positive cosmological constant on spherically symmetric dust collapse. We take the FRW metric in the interior region whereas Schwarzschild-de Sitter in the exterior region. The matching conditions between exterior and interior spacetimes are given in the presence of a cosmological constant. We also discuss the apparent horizons and their physical significance.

Gravitational Perfect Fluid Collapse With Cosmological Constant
In this paper, the effect of a positive cosmological constant on spherically symmetric collapse with perfect fluid has been investigated. The matching conditions between static exterior and non-static interior spacetimes are given in the presence of a cosmological constant. We also study the apparent horizons and their physical significance. It is concluded that the cosmological constant slows ...
متن کاملMatching Conditions and Gravitational Collapse in Two-Dimensional Gravity
The general theory of matching conditions is developed for gravitational theories in two spacetime dimensions. Models inspired from general relativity and from string theory are considered. These conditions are used to study collapsing dust solutions in spacetimes with non-zero cosmological constant, demonstrating how two-dimensional black holes can arise as the endpoint of such collapse proces...
متن کامل0 Gravitational Collapse and Cosmological Constant
We consider here the effects of a non-vanishing cosmological term on the final fate of a spherical inhomogeneous collapsing dust cloud. It is shown that depending on the nature of the initial data from which the collapse evolves, and for a positive value of the cosmological constant, we can have a globally regular evolution where a bounce develops within the cloud. We characterize precisely the...
متن کاملFinal fate of spherically symmetric gravitational collapse of a dust cloud in Einstein-Gauss-Bonnet gravity
We give a model of the higher-dimensional spherically symmetric gravitational collapse of a dust cloud including the perturbative effects of quantum gravity. The n(≥ 5)-dimensional action with the Gauss-Bonnet term for gravity is considered and a simple formulation of the basic equations is given for the spacetime M ≈ M × K with a perfect fluid and a cosmological constant. This is a generalizat...
متن کاملInhomogeneous cosmologies with tachyonic dust as dark matter
A cosmology is considered driven by a stress-energy tensor consisting of a perfect fluid, an inhomogeneous pressure term (which we call a " tachyonic dust " for reasons which will become apparent) and a cosmological constant. The inflationary , radiation dominated and matter dominated eras are investigated in detail. In all three eras, the tachyonic pressure decreases with increasing radius of ...
