Abstract

This article explores the impact of charge on the properties of relativistic compact star candidates exhibiting anisotropic distribution in f(Q) gravity, where Q represents a nonmetricity. A specific model of this gravitational theory is considered to simplify the system and establish the precise field equations that regulate the interaction between matter and geometry. Analysis of the static spherical symmetric structures is conducted by considering the non-singular feasible solutions. The Darmois constraints are used to determine the unknown constants in the metric coefficients. We explore different physical characteristics in the interior of charged compact stars to check their viability. Sound velocity and adiabatic index techniques are employed for stability state analysis. Proposed charged stars are determined to be both viable and stable in this theoretical framework.

f(Q)重力校正带电各向异性溶液的物理可行性
本文探讨了电荷对f(Q)引力中表现出各向异性分布的相对论性致密星候选者性质的影响,其中Q表示非对称性。考虑了该引力理论的一个特定模型来简化系统并建立精确的场方程来调节物质与几何之间的相互作用。考虑非奇异可行解,对静力球对称结构进行了分析。利用达摩约束确定度规系数中的未知常数。我们探索了带电致密恒星内部的不同物理特性,以检查它们的生存能力。稳定状态分析采用声速和绝热指数技术。在这个理论框架下,提出的带电恒星既可行又稳定。
