摘要

我们根据电荷Q参数找到了Kerr-Newman黑洞的质量M和旋转a参数，以及在旋转和反旋转两种情况下，测地粒子在其周围的圆形轨道上运动时发出的光的红色zr和蓝色zb位移。这些位移zr和zb不能获得任意值；这些位移的边界是参数a和Q的函数。

On the relation of the mass, spin and charge parameters with the red and blue shifts of photons emitted by particles orbiting a Kerr–Newman black hole

We found the mass M and rotation a parameters of the Kerr–Newman black hole in terms of the charge Q parameter as well as the red zr and blue zb shifts of light emitted by geodesic particles traveling in circular orbits around it for both cases: corotating and counterrotating directions. These shifts zr and zb cannot acquire arbitrary values; bounds of these shifts are found as functions of the parameters a and Q.
