论文摘要
本文研究了电荷对紧凑型恒星结构的影响，也被视为$ f（\ mathfrak {r}，\ mathcal {t}^{2} {2}）的背景中的真空冷凝物星。该物体被认为是黑洞的替代物，其结构涉及三个不同的区域，即内部，外部和薄壳。我们为这种修改理论的特定模型分析了rAVASTAR的这些域。在Grastar的内部区域中，所考虑的状态方程定义了能量密度等于负压，这是球形壳上排斥力的原因。在中间壳中，压力和能量密度相等，并含有超相关的流体。薄壳的向内引力平衡的重力平衡的力是由重力的内部区域施加的力，允许形成无奇异物体的物体。 Reissner-Nordstrom度量标准介绍了外部真空球形域。此外，我们讨论了电荷对降压物物理属性的影响，例如状态参数，熵，适当的长度和能量。我们得出的结论是，在这一修改的理论中，带电的Grastar的无奇异溶液在物理上是一致的。
This paper studies the influence of charge on a compact stellar structure also regarded as vacuum condensate star in the background of $f(\mathfrak{R},\mathcal{T}^{2})$ gravity. This object is considered the alternate of black hole whose structure involves three distinct regions, i.e., interior, exterior and thin-shell. We analyze these domains of a gravastar for a particular model of this modified theory. In the inner region of a gravastar, the considered equation of state defines that energy density is equal to negative pressure which is the cause of repulsive force on the spherical shell. In the intermediate shell, pressure and energy density are equal and contain ultra-relativistic fluid. The inward-directed gravitational pull of thin-shell counterbalance the force exerted by the inner region of a gravastar allowing the formation of a singularity-free object. The Reissner-Nordstrom metric presents the outer vacuum spherical domain. Moreover, we discuss the impact of the charge on physical attributes of a gravastar such as the equation of state parameter, entropy, proper length and energy. We conclude that singularity-free solutions of charged gravastar are physically consistent in this modified theory.
