    New solutions for charged anisotropic fluid spheres in general relativity

    The general analytical solutions for charged fluid distribution with anisotropic pressure are obtained. These solutions depend on an arbitrary generating function and the choice of an anisotropic function whic...

    A unified approach to charged-fluid distributions in general relativity

    The exact solutions for a charged perfect fluid are derived. The general analytical solution obtained depends on an arbitrary function of one of the space coordinates. As an illustration of the proposed method...

    Solutions of einstein's field equations for charged static fluid spheres

    In this paper the authors have extended Bayin's (1978) work to the case of charged fluid spheres. These solutions are matched at the boundary with the Reissner-Nordström solution.
