Relativistic anisotropic charged fluid spheres with varying cosmological con- stant

چکیده
Static spherically symmetric anisotropic source has been studied for the EinsteinMaxwell field equations assuming the erstwhile cosmological constant Λ to be a space-variable scalar, viz., Λ = Λ(r). Two cases are examined out of which one reduces to isotropic sphere. The solutions thus obtained are shown to be electromagnetic in origin as a particular case. It is also shown that the generally used pure charge condition, viz., ρ+ pr = 0 is not always required for constructing electromagnetic mass models. PACS number(s): 04.20.-q, 04.20.Jb

Relativistic Stellar Models with Quadratic Equation of State
In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...
متن کاملRelativistic fluid spheres with particular application in cosmology and gravitational collapse
A spherically symmetric comoving fluid solution of Einstein’s equations is adapted for cosmological application by extending the geometry of standard FRW cosmology using a generalised curvature term. The resulting model retains many of the known cosmological properties including homogeneity of energy density, its relationship with internal pressure including equations of state, although in each...
متن کاملSelf–similar and Charged Radiating Spheres: an Anisotropic Approach
Considering charged fluid spheres as anisotropic sources and the diffusion limit as the transport mechanism, we suppose that the inner space– time admits self–similarity. Matching the interior solution with the Reissner– Nordström–Vaidya exterior one, we find an extremely compact and oscillatory final state with a redistribution of the electric charge function and non zero pressure profiles.
متن کاملInstability of Extremal Relativistic Charged Spheres
With the question, “Can relativistic charged spheres form extremal black holes?” in mind, we investigate the properties of such spheres from a classical point of view. The investigation is carried out numerically by integrating the Oppenheimer-Volkov equation for relativistic charged fluid spheres and finding interior Reissner-Nordström solutions for these objects. We consider both constant den...
