Abstract
A charged analogue of Schwarzschild’s interior solution has been derived by considering the non-gravitational energy density to be constant along with a special choice of electric intensity. The charged fluid sphere so obtained is seen to be more general than that of P.S. Florides and joins smoothly with the Reissner-Nordstrom metric at the pressure-free interface. Also the new charged fluid sphere is capable of representing a superdense star with surface density of 2×1014 g cm−3 which can occupy maximum mass 1.502408 times the solar mass. In the process of deriving the solution, the authors have also come across A. L. Mehra’s gaseous charged fluid model which is found to be unphysical as it has negative pressure at least at the center of the model.
