近极值Kerr-Newman黑洞的拟正态共振

Quasinormal resonances of near-extremal Kerr-Newman black holes

Shahar Hod

摘要:

本文研究了近极值慢旋转Kerr-Newman黑洞的基本共振。我们找到了这些黑洞准正规频率与黑洞物理参数的简单解析表达式:Ω =m Ω-2 i π T(l+1+n),其中T和Ω分别是黑洞的温度和角速度.模式参数l和m分别是同向旋转模式的球谐指数和方位谐指数。这个解析公式在Im ω << Re ω <<1/M的情况下是有效的,其中M是黑洞质量。

英文摘要:

We study analytically the fundamental resonances of near-extremal, slowly rotating Kerr-Newman black holes. We find a simple analytic expression for these black-hole quasinormal frequencies in terms of the black-hole physical parameters: omega=m Omega-2i pi T(l+1+n), where T and Omega are the temperature and angular velocity of the black hole. The mode parameters l and m are the spheroidal harmonic index and the azimuthal harmonic index of a co-rotating mode, respectively. This analytical formula is valid in the regime Im omega << Re omega <<1/M, where M is the black-hole mass.
