Type II Fluid Solutions to Einstein’s Field Equations in N-Dimensional Spherical Spacetimes

چکیده
A large class of Type II fluid solutions to Einstein field equations in Ndimensional spherical spacetimes is found, wich includes most of the known solutions. A family of the generalized collapsing Vaidya solutions with homothetic self-similarity, parametrized by a constant λ, is studied, and found that when λ > λc(N), the collapse always forms black holes, and when λ < λc(N), it always forms naked singularities, where λc(N) is function of the spacetime dimension N only.

On Einstein’s Equations for Spacetimes Admitting a Non–Null Killing Field
We consider the 3-dimensional formulation of Einstein’s theory for spacetimes possessing a non-null Killing field ξ. It is known that for the vacuum case some of the basic field equations are deducible from the others. It will be shown here how this result can be generalized for the case of essentially arbitrary matter fields. The systematic study of the structure of the fundamental field equat...
متن کاملGravity of higher-dimensional global defects
Solutions of Einstein’s equations are found for global defects in a higherdimensional spacetime with a nonzero cosmological constant Λ. The defect has a (p − 1)-dimensional core (brane) and a ‘hedgehog’ scalar field configuration in the n extra dimensions. For Λ = 0 and n > 2, the solutions are characterized by a flat brane worldsheet and a solid angle deficit in the extra dimensions. For Λ > 0...
متن کاملv 1 2 8 N ov 1 99 8 Spacetime Exterior to a Star
In many circumstances the perfect fluid conservation equations can be directly integrated to give a Geometric-Thermodynamic equation: typically that the lapse N is the reciprocal of the enthalphy h, (N = 1/h). This result is aesthetically appealing as it depends only on the fluid conservation equations and does not depend on specific field equations such as Einstein’s. Here the form of the Geom...
متن کاملSome Static Isotropic Perfect Fluid Spheres in General Relativity
In the present article, a new class of solutions of Einstein field equations is investigated for a spherically symmetric space-time when the source of gravitation is a perfect fluid. All the solutions have been derived by making some suitable arrangements in the field equations. The solutions so obtained have been seen to describe Schwarzschild interior solutions. Most of the solutions are subj...
متن کامل2+1-dimensional black holes with momentum and angular momentum
Exact solutions of Einstein’s equations in 2+1-dimensional anti-de Sitter space containing any number of black holes are described. In addition to the black holes these spacetimes can possess “internal” structure. Accordingly the generic spacetime of this type depends on a large number of parameters. Half of these can be taken as mass parameters, and the rest as the conjugate (angular) momenta....
