A Class of Charged Relativistic Superdense Star Models

Abstract

In this article we obtain a new class of well behaved charged solutions by using particular forms of the metric potential g 44 and electric intensity, which involves a parameter K. The metric describing the superdense stars joins smoothly with the Reissner-Nordstrom metric at the pressure free boundary. This class of solutions describes well behaved charged fluid balls. The class of solutions gives range of parameter K (0.13≤K≤1.9999) for which the solution is well behaved hence, suitable for modeling of super dense star. The interior of the stars possess there energy density, pressure, pressure-density ratio and velocity of sound to be monotonically decreasing towards the pressure free interface. In view of the surface density 2×10 14 gm/cm 3, the maximum mass of the charged fluid balls and corresponding radius are 0.4711M Θ and 7.0122 km. The red shift at the centre and boundary are found to be 0.1640 and 0.1100 respectively. © 2011 Springer Science+Business Media, LLC.
