In this work we investigate the Rastall-Maxwell theory around the strange quark matter (SQM). Some solutions are obtained by solving the Modified Tolman-Oppenheimer-Volkoff (TOV) equation in the framework of Rastall gravity. Analysis are performed about the energy condition, the mass-radius relation, the modified TOV equation, the redshift and the stability of the system is checked by exploring the adiabatic index, the compactification factor and the causality condition in order to verify the physical consistency of our model. It comes from our results that for physical values of Rastall parameter, the stellar system is more massive compared to its size. Hence, it emerges from our work that the alternative Rastall theory is a suitable candidate to explain the behavior of massive stellar objects.

各向异性带电奇异星的 Rastall-Maxwell 方法

在这项工作中,我们研究了围绕奇异夸克物质 (SQM) 的 Rastall-Maxwell 理论。一些解是通过在 Rastall 重力框架中求解修正的 Tolman-Oppenheimer-Volkoff (TOV) 方程获得的。对能量条件、质量半径关系、修正的TOV方程、红移进行分析,通过探索绝热指数、压实因子和因果关系来检验系统的稳定性,以验证系统的物理一致性。我们的模型。它来自我们的结果,对于 Rastall 参数的物理值,恒星系统与其大小相比更大。因此,从我们的工作中可以看出,另一种 Rastall 理论是解释大质量恒星物体行为的合适候选者。
