Compact stars with quadratic equation of state
Sifiso A. Ngubelanga, Sunil D. Maharaj, Subharthi Ray
We provide new exact solutions to the Einstein-Maxwell system of equations for matter configurations with anisotropy and charge. The spacetime is static and spherically symmetric.…
Compact stars with linear equation of state in isotropic coordinates
Sifiso A. Ngubelanga, Sunil D. Maharaj, Subharthi Ray
We present a new class of spherically symmetric spacetimes for matter distributions with anisotropic pressures in the presence of an electric field. The equation of state for the m…
Quark star model with charged anisotropic matter
Jefta M. Sunzu, Sunil D. Maharaj, Subharthi Ray
We find two new classes of exact solutions to the Einstein-Maxwell system of equations. The matter distribution satisfies a linear equation of state consistent with quark matter. T…
Charged anisotropic models for quark stars
Jefta M. Sunzu, Sunil D. Maharaj, Subharthi Ray
We perform a detailed physical analysis for a class of exact solutions for the Einstein-Maxwell equations. The linear equation of state consistent with quark stars has been incorpo…
Stellar objects in the quadratic regime
P. Mafa Takisa, S. D. Maharaj, Subharthi Ray
We model a charged anisotropic relativistic star with a quadratic equation of state. Physical features of an exact solution of the Einstein-Maxwell system are studied by incorporat…
Charged compact objects in the linear regime
P. Mafa Takisa, S. Ray, S. D. Maharaj
Astrophysical compact stars provide a natural laboratory for testing theoretical models which are otherwise difficult to prove from an experimental setup. In our present work we an…
