Analysis of minimum orbital periods around d-dimensional charged black holes
Yan Peng, Guohua Liu
This paper investigates the bounds on the minimum orbital period for test objects around d-dimensional charged black holes in asymptotically flat spacetimes. We find numerically th…

Bounds on the minimum orbital periods of non-singular Hayward and Bardeen black holes
Guohua Liu, Yan Peng
Based on previous studies, universal bounds were conjectured to be characteristic properties of black hole spacetimes, where rep…
