论文摘要
在这项工作中，我们研究了一类常规黑洞解决方案的准频率，这些频率概括了Bardeen和Hayward的空间。特别是，我们使用半分析WKB方法及其时间域谱分析了黑洞的标量，矢量和重力扰动。我们详细分析了频谱的行为，具体取决于黑洞的参数$ p/q $，角动量的量子数和$ s $。此外，我们将结果与经典解决方案进行比较，对$ p = q = 1 $有效。
In this work, we investigate the quasinormal frequencies of a class of regular black hole solutions which generalize Bardeen and Hayward spacetimes. In particular, we analyze scalar, vector and gravitational perturbations of the black hole both with the semianalytic WKB method and their time-domain profiles. We analyze in detail the behavior of the spectrum depending on the parameter $p/q$ of the black hole, the quantum number of angular momentum and the $s$ number. In addition, we compare our results with the classical solution valid for $p = q = 1$.
