Abstract

The major goal of this study is to investigate the structure of a thin-shell by matching the inner flat and exterior hairy Schwarzschild black holes using Visser’s approach. Then, by using the equation of motion and the Klein–Gordon equation, we investigate the evolutionary behavior of a thin-shell composed of scalar fields (massive and massless). It is noticed that the potential function of a massless scalar shell exhibits collapsing behavior, whereas the case of a massive scalar shell exhibits collapsing behavior initially and then gradually expands. Finally, thin-shell stability is observed by using the perturbed form of potential function at equilibrium shell radius with the phantom-like equation of state, i.e., quintessence, dark energy, and phantom energy. It is noted that stable/unstable behavior of thin-shell is found after the expected position of the event horizon of the exterior manifold. Finally, it is concluded that the thin-shell stability of Schwarzschild geometry is more than the hairy Schwarzschild black hole.

标量场对带毛状史瓦西黑洞薄壳动力学演化的影响

这项研究的主要目标是通过使用维瑟的方法匹配内部扁平和外部毛茸茸的史瓦西黑洞来研究薄壳的结构。然后，利用运动方程和Klein-Gordon方程，研究了由标量场(有质量场和无质量场)组成的薄壳的演化行为。注意到无质量标量壳层的势函数表现出坍缩行为，而有质量标量壳层的势函数表现出先坍缩后逐渐扩大的行为。最后，利用平衡壳半径处势函数的摄动形式和类幻态方程(即精质、暗能量和幻能)来观察薄壳的稳定性。注意到薄壳的稳定/不稳定行为出现在外部流形的视界期望位置之后。最后，得出了史瓦西几何的薄壳稳定性比毛状史瓦西黑洞更强的结论。
