摘要
Assuming an anisotropic pressure and a quadratic equation of state for the matter distribution, we obtain two new classes of static spherically-symmetric solutions of the Einstein-Maxwell field equations. The solutions presented here extend the work presented by T. Feroze (Canadian J. Phys. 90(12), 1179 (2012)).
