A unified topological classification of circular orbits for charged particles in black hole spacetimes
Yong Song, Jia Li, Yiting Cen +3
The study of circular orbits offers profound insights into the structure of spacetime around black holes. While the topological properties of these orbits are well-established for…

The particle surface of spinning test particles
Yong Song, Yiting Cen, Leilei Tang +4
In this work, inspired by the definition of the photon surface given by Claudel, Virbhadra, and Ellis, we give an alternative quasi-local definition to study the circular orbits of…
