论文摘要
我们计算在旋转黑洞的赤道平面上的圆形测量轨道上作用在带电粒子上的自力。我们通过直接计算显示，耗散的自力量平衡与辐射到无穷大的通量和通过黑洞地平线的总和。发现训练轨道可刺激黑洞的超赞，但我们确认无法满足浮动轨道的条件。我们通过应用模式和正规化方法来计算自我强制的保守组成部分，并提出了数值结果的选择。通过数值拟合，我们提取牛顿后扩展中的前阶系数。计算了Kerr时空的最内向圆形轨道上的自力，并在电磁和引力自我力量之间进行了比较。
We calculate the self-force acting on a charged particle on a circular geodesic orbit in the equatorial plane of a rotating black hole. We show by direct calculation that the dissipative self-force balances with the sum of the flux radiated to infinity and through the black hole horizon. Prograde orbits are found to stimulate black hole superradiance, but we confirm that the condition for floating orbits cannot be met. We calculate the conservative component of the self-force by application of the mode sum regularization method, and we present a selection of numerical results. By numerical fitting, we extract the leading-order coefficients in post-Newtonian expansions. The self-force on the innermost stable circular orbits of the Kerr spacetime is calculated, and comparisons are drawn between the electromagnetic and gravitational self forces.
