AI 中文摘要
应用于黑洞视界的非广延熵模型通过Wald熵形式主义与广义爱因斯坦-希尔伯特作用量、f(R)引力理论相联系。我们证明，在这种修正引力方法下，由MIT袋模型表征的夸克星构型符合与HESS J1731-347和GW190814相关的致密天体的观测上下限。此外，我们评估有效能量条件和相应的声速，以评估恒星构型的物理合理性和稳定性，所有研究的非广延熵模型均满足这些条件。我们的发现表明，奇异致密天体为探索Barrow、Tsallis-Cirto和Rényi等非广延熵模型的各个方面提供了令人信服且可信的框架，反之亦然。
英文摘要
The non-extensive entropy models applied to the black-hole horizon are connected to the generalized Einstein--Hilbert action, $f(R)$, via the Wald entropy formalism. We demonstrate that quark star configurations characterized by the MIT bag model under this modified gravity approach conform to the observational lower and upper bounds established for compact objects linked to HESS J1731$-$347 and GW190814. Furthermore, we assess the effective energy conditions and corresponding speed of sound to evaluate the physical plausibility and stability of the stellar configurations. All non-extensive entropy models studied satisfied these conditions. Our findings show that the exotic compact objects offer a compelling and credible framework for exploring aspects of non-extensive entropy models, such as the Barrow, Tsallis-Cirto, and Rényi formalisms, and vice versa.
