F(R)引力下扩展黑洞的标量和电磁准正规模

Scalar and Electromagnetic Quasinormal modes of Extended black hole in F(R) gravity

Saneesh Sebastian, V. C. Kuriakose

摘要:

本文研究了扩展黑洞在F(R)引力中的标量扰动和电磁扰动。在两种情况下的准正规模式进行评估和研究,在每种情况下绘制图形,他们的行为。为了研究准正规模,我们采用三阶WKB方法。研究表明,在这两种情况下,复拟正规模的虚部的绝对值都增加,因此黑洞对这些扰动是稳定的。当标量场的质量增加时,频率的虚部减小。因此,阻尼随着标量场质量的增加而减慢。

英文摘要:

In this paper we study the scalar and electromagnetic perturbations of an extended black hole in F(R) gravity. The quasinormal modes in two cases are evaluated and studied their behavior by plotting graphs in each case. To study the quasinormal mode, we use the third order WKB method. The present study shows that the absolute value of imaginary part of complex quasinormal modes increases in both cases, thus the black hole is stable against these perturbations. As the mass of the scalar field increases the imaginary part of the frequency decreases. Thus damping slows down with increasing mass of the scalar field.
