Quasi-spherical collapse with cosmological constant

Gravitational collapse is one of the most important problem in classical general relativity. Usually, the formation of compact stellar objects such as white dwarf and neutron star are preceded by a period of collapse. Hence for astrophysical collapse, it is necessary to describe the appropriate geometry of interior and exterior regions and to determine proper junction conditions which allow the...

The Spherical Collapse Model in a Universe with Cosmological Constant

The spherical collapse model was first developed by Gunn & Gott 1 for a flat universe with no cosmological constant. It assumes that the process of formation of bound objects in the universe can be at first approximation described by evolution of an uniformly overdense spherical region in otherwise smooth background. Despite its simplicity, the model has been widely used to explain properties o...

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 ...

Gravitational Dust Collapse with Cosmological Constant

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 signific...

Spherical symmetric charged solution with cosmological constant

A spherically symmetric charged ideal fluid solution of Einstein field equation is given in the presence of the cosmological constant and two well known example of this type of solution is presented. If the matter is confined in a region, the exterior spacetime is considered as RN-de Sitter (Reissner-Nordström de Sitter) and to complete solution matching conditions are examined. We show that th...
