论文摘要
本文研究了常规空间（Bardeen和Bardeen-de保姆黑洞）的薄壳静脉的稳定性。我们应用切割和糊状方法，通过与外部常规黑洞的内部非单明性DE STINTER几何形状匹配来构建静态。该模型包含三个区域，即内部，薄壳和外部。内部和外部区域在薄壳上连接。我们通过能量条件研究了开发模型的物理生存力，并通过使用径向扰动壳壳半径来探索其稳定性。发现与Bardeen Black Hole相比，Bardeen-De Sitter黑洞的薄壳静脉显示了大型稳定区域。可以得出结论，稳定区域存在于预期事件范围的形成附近。
This paper examines the stability of thin-shell gravastars in the context of regular spacetimes (Bardeen and Bardeen-de Sitter black holes). We apply cut and paste approach to construct gravastars through the matching of interior non-singular de Sitter geometry with exterior regular black hole. This model contains three regions, i.e., interior, thin-shell and exterior. The interior and exterior regions are connected at thin-shell. We investigate physical viability of the developed model by the energy conditions and explore its stability by using radial perturbation about the equilibrium shell radius. It is found that thin-shell gravastars show large stable regions for the Bardeen-de Sitter black hole as compared to the Bardeen black hole. It is concluded that stable regions exist near the formation of expected event horizon.
