摘要

本文探讨了重力中的引力星的特征，该引力星由 Krori-Barua (KB) 公设支持。作者在引力星的内部和外壳区域使用了 KB 公设。利用 KB 公设推导出了场方程。在引力星的外部区域，采用了两种常规黑洞度量。此外，还应用了以色列结条件来计算薄壳上的电势差，涉及不同类型的规则黑洞，如巴丁黑洞和海沃德黑洞。此外，还讨论了适当长度、熵、能量、状态方程和稳定性等物理特性。

Gravastar Model in Krori–Barua Metric Under f ( Q ) $f(\mathcal {Q})$ Gravity

In this paper, the characteristics of a gravastar in $f (Q)$ gravity, which is upheld by Krori–Barua (KB) metric are explored. The authors have used KB metric for the interior and shell regions of the gravastar. The field equations are deduced by using KB metric. In the outside regions of the gravastar, two regular black hole metrics are taken. Additionally, the Israel junction condition to calculate the potential difference across the thin shell concerning different types of regular black holes, such as Bardeen and Hayward is applied. The physical properties like proper length, entropy, energy, equation of state, and stability are also discussed.

期刊介绍： The journal Fortschritte der Physik - Progress of Physics is a pure online Journal (since 2013). Fortschritte der Physik - Progress of Physics is devoted to the theoretical and experimental studies of fundamental constituents of matter and their interactions e. g. elementary particle physics, classical and quantum field theory, the theory of gravitation and cosmology, quantum information, thermodynamics and statistics, laser physics and nonlinear dynamics, including chaos and quantum chaos. Generally the papers are review articles with a detailed survey on relevant publications, but original papers of general interest are also published.
