Abstract
We obtain a new class of charged super-dense star models after prescribing particular Forms of the metric potential and electric intensity. The metric describing the superdense stars joins smoothly with the Reissner-Nordstrom metric at the pressure free boundary. The interior of the stars possess their 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 <i>ρ<sub>b</sub></i>=2×10<sup>14</sup>g/cm<sup>3</sup>, the heaviest star occupies a mass 5.523 <i>M</i><sub>⊙</sub>with its radius 13.98 km. In absence of the charge we are left behind with the regular and well behaved fifth model of Durgapal [1].
