摘要

在这项研究中，我们建立了一个带电恒星模型，该模型有三层，具有不同的状态方程。核心层、中间层和包膜层分别服从线性、多向性和查普里金状态方程。该模型满足物质变量、引力势和稳定性条件的物理要求。我们为恒星生成了可接受范围内的质量和半径。我们还从早期的研究中恢复了PSRJ1903+0327、PSRJ1614-2230、SAXJ1808.4-3658、Vela X-1和EXO1785-248等恒星的质量和半径，这显示了我们模型的天体物理学意义。

Charged anisotropic composite stellar object with strange, polytropic and gaseous matter

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.
