论文摘要
我们提出了从Kerr黑洞的最内向稳定的圆形轨道（ISCO）向内螺旋的测试粒子轨道的精确溶液。我们的结果对于KERR公制的Angular Momentum $ a $参数的任何允许的值都是有效的。这些解决方案具有很大的身体利益。特别是，这些轨道的径向4速度都非常简单，并且径向坐标按其ISCO值缩放，形式为通用，否则完全独立于黑洞旋转。
We present exact solutions of test particle orbits spiralling inward from the innermost stable circular orbit (ISCO) of a Kerr black hole. Our results are valid for any allowed value of the angular momentum $a$-parameter of the Kerr metric. These solutions are of considerable physical interest. In particular, the radial 4-velocity of these orbits is both remarkably simple and, with the radial coordinate scaled by its ISCO value, universal in form, otherwise completely independent of the black hole spin.
