摘要
We find new stellar models to the field equations for charged anisotropic spheres. We use linear quark equation of state for strange quark matter. We choose a new form of pressure anisotropy as a rational function. In our model, we regain previous isotropic and anisotropic stellar models as specific cases. Isotropic models regained are those found by Komathiraj and Maharaj, Mak and Harko, and Misner and Zapolsky. Anisotropic models regained include the performance by Maharaj, Sunzu and Ray; and Sunzu and Danford. We indicate that our model meets the stability and energy conditions. We also generate stellar masses consistent with observations.
