    Charged Anisotropic Composite Stellar Object with Strange, Polytropic and Gaseous Matter
    (Elsevier BV, 2023) Olengeile, Lilian; Sunzu, Jefta M.; Mkenyeleye, Jason Maombi
    In this study, we build a charged star model with three layers with distinct equations of state. The core, intermediate layer, and envelope layer obey linear, polytropic, and Chaplygin equations of state, respectively. The model satisfies the physical requirements for the matter variables, gravitational potentials, and stability conditions. We have generated within-acceptable range masses and radii for stars. We also recover the masses and radii for the stars PSRJ1903+0327, PSRJ1614-2230, SAXJ1808.4-3658, Vela X-1, and EXO1785-248 from earlier investigations which shows astrophysical significance of our model.
