广义Schwarzschild黑洞的电磁扰动拟正则模

Electromagnetic Quasi-Normal Modes of Generalized Schwarzschild Black Holes

研究了广义 Schwarzschild黑洞的电磁扰动 ,得到了广义 Schwarzschild黑洞外部时空中电磁势所满足的微分方程 ,讨论了 3种情况下方程中的等效势函数 V与 r* 的关系 ,并用数值计算的方法得到了相应的拟正则模 .

We have studied the electromagnetic perturbation of a Generalized Schwarzschild black hole; obtained the differential equation of the electromagnetic potential in the external space-time of the black hole; discussed the characteristics of the effective potential V depending on r_* in three different cases. And also we have calculated the quasi-normal frequencies with numerical method.
