论文摘要
我们在近高级凯尔黑洞的近野孔区域中提供了详尽的插图分类。极性运动的分类延伸至任意自旋的Kerr黑色孔。径向运动的分类导致界和未结合运动之间的分离质的简单参数化。此外，我们证明每个时间级或无效的测量都通过共形变换和与球形轨道的离散对称性相关，并且我们提供明确的映射。我们详细介绍了最内向的稳定和最内向的球形轨道的高旋转行为。
We provide an exhaustive and illustrated classification of timelike and null geodesics in the near-horizon region of near-extremal Kerr black holes. The classification of polar motion extends to Kerr black holes of arbitrary spin. The classification of radial motion leads to a simple parametrization of the separatrix between bound and unbound motion. Furthermore, we prove that each timelike or null geodesic is related via conformal transformations and discrete symmetries to spherical orbits and we provide the explicit mappings. We detail the high-spin behavior of both the innermost stable and the innermost bound spherical orbits.
