利用Teukolsky（1973）方法构造了Kerr时空中无质量标量、电磁和引力扰动的辐射绿色函数。作用在测试粒子上的反作用力，它可以发射任何自旋s=0，1，2的辐射，计算和示出正确的帐户的能量和角动量带走的辐射到无穷大和事件视界。的反作用力的方位角分量被发现保持有限的粒子在静止的Boyer-Lindquist坐标由于非零角动量转移到旋转孔。这种辐射反应的反常静力是对霍金潮汐摩擦的反作用。
The radiative Green functions for the massless scalar, electromagnetic and gravitational perturbations of the Kerr space-time are constructed using the Teukolsky (1973) formalism. The reaction force acting upon a test particle, which can emit radiation of any spin s=0, 1, 2, is calculated and shown to account correctly for the energy and the angular momentum carried away by radiation to infinity and to the event horizon. The azimuthal component of the reaction force is found to remain finite for a particle at rest in the Boyer-Lindquist coordinates owing to non-zero angular momentum transfer to the rotating hole. This anomalous static force of radiation reaction emerges as the counteraction to Hawking's tidal friction.
