用高阶WKB方法研究多毛黑洞的准正规模

Quasi Normal Modes of hairy black holes at higher--order WKB approach

Roberto Avalos, Ernesto Contreras

摘要:

在这项工作中,我们实现了$13^{th}$阶半解析WKB方法来探讨引力解耦框架下获得的多毛黑洞的稳定性。特别是,我们进行了详细的分析的准正常模式的频率作为一个功能的主要头发的解决方案,其目的是约束其值。我们探索了一个广泛的区间,在一个步骤的0.1的头发参数。我们发现,除了在某些情况下,该方法预计将有不良的准确性,所有的解决方案似乎是稳定的,所发挥的作用是双重的:调制阻尼因子的扰动和降低其振荡的频率。

英文摘要:

In this work, we implement the $13^{th}$ order semi-analytical WKB method to explore the stability of hairy black holes obtained in the framework of Gravitational Decoupling. In particular, we perform a detailed analysis of the frequencies of the quasi-normal modes as a function of the primary hair of the solutions with the aim to bound their values. We explore a broad interval in a step of 0.1 of the hair parameters. We find that except for some cases where the method is expected to have poor accuracy, all the solutions seem to be stable and the role played by the primary hair is twofold: to modulate the damping factor of the perturbation and to decrease the frequency of its oscillation.
