标题： Constraining study of charged gravastars solutions in symmetric teleparallel gravity

摘要： 这项研究探讨了电荷对一种特殊的天体物理对象——引力星（gravastar）的影响，它被视为黑洞的一种替代方案。 基于Mazur和Mottola在广义相对论中提出的假设，本研究主要关注$f(Q)$引力的后果。 内部区域、中间壳层和外部区域是构成引力星的三个独立部分。 使用一种特定的$f(Q)$引力模型，该模型包含共形 Killing 向量来分析这些区域，我们发现由于假设压力等于负能量密度，内部区域对球形壳层表现出排斥力。 中间壳层由超相对论性等离子体和压力组成，压力与能量密度成正比，并平衡来自内部区域的排斥力。 对于外部区域，我们采用两种方法：首先计算真空精确解，其次将其视为Reissner-Nordström度规。 然后，我们通过匹配条件将这些时空连接起来，并探讨两种情况下的稳定性约束。 我们的结果表明，具有非奇异物理参数（包括长度、能量、熵和状态方程参数）的带电引力星解在物理上是现实的。 显示英文摘要

摘要： This study explores the effect of charge on a special astronomical object known as a gravastar, which is viewed as an alternative to a black hole. Based on the conjecture put out by Mazur and Mottola in general relativity, the study primarily focuses on the consequences of $f(Q)$ gravity. The internal domain, the intermediate shell, and the external domain are the three separate sections that make up a gravastar. Using a particular $f(Q)$ gravity model that includes conformal Killing vectors to analyze these areas, we discover that the inner domain shows a repulsive force on the spherical shell since it is assumed that pressure is equivalent to negative energy density. The intermediate shell is made up of ultrarelativistic plasma and pressure, which is proportional to energy density and balances the repulsive force from the interior domain. For exterior region, we use two appraoches as first we calculate the vacuum exact solution and secondly considered as the Reissner-Nordstr\"om metric. Then, we match these spacetimes through junction condition and explore the stability constraints for both cases. Our results show that charged gravastar solutions with non-singular physical parameters including length, energy, entropy, and equation of state parameter are physically realistic.
