“…In the recent past, realistic solutions corresponding to Einstein-Maxwell systems describing various physically motivated astrophysical objects, have been developed and analyzed by many researchers which include Ref. [28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57]. In the absence of any reliable information about the equation of state (EOS) at extreme densities assumption of one of the metric potentials, based on geometry of the associated 3-space, has been found to be a reasonable technique to construct both charged and uncharged stellar models.…”

In this paper a compact charged stellar model in the Finch and Skea background spacetime [{\it Class. Quantum Gravity} {\bf6}, 467 (1989)] is presented. The model has been developed by assuming a particular charge distribution within the stellar interior. The model is well behaved and can describe a large class of compact stars. Physical features of the model are studied and in particular we show how the presence of charge can have a non-negligible impact on the mass-radius ($M-R$) relationship of such class of stars.Comment: 14 pages, 9 figure

In the present paper we have found some solutions of Einstein-Maxwell Field equations for some charged fluid sphere. Assuming that the spin of the individual particles compositing the fluids are all aligned along radial direction, we have obtained solutions by choosing metric potentials as λ(r) and υ(r) on different suitable forms or conditions. Pressure and density have been also calculated for the distribution and the physical constants appearing in the solution have been evaluated by matching the solutions to the Reissner-Nordstrom metric at the boundary. It is found that our metric give the solutions to only that value of constants for which pressure and density are positive. Also some physical and kinematical properties of the models are discussed.

“…The presence of charge affects values for redshifts, luminosity and maximum mass for stars astrophysics where the gravitational fields are strong are described by solutions of the coupled Einstein-Maxwell system of equations. More over the charged analogues of the said anisotropic models further improved the situation [32,33,34]. Lake [3] and Herrera et al [35] have developed the algorithm for all spherical symmetric solutions corresponding to perfect and anisotropic fluid distribution respectively.…”

A charged compact star model has been determined for anisotropic fluid distribution. We have solved the Einstein's-Maxwell field equations to construct the charged compact star models by using radial pressure, metric function e λ and electric charge function. The generic charged anisotropic solution is verified by exploring different physical conditions like, causality condition, mass-radius relation and stability of the solution (via. adiabatic index, TOV equations and Herrera cracking concept). It is observed that the present charged anisotropic compact star is compatible with the star PSR 1937+21. However we also presented the EOS ρ = f (p) for present charged compact star model.
