Precession of spherical orbits for the spacetime without symmetry induced by NUT charge
Xiang-Cheng Meng, Shan-Ping Wu, Shao-Wen Wei
Astrophysical evidence has hinted at the existence of a nonzero NUT charge, which breaks the symmetry of spacetime and induces novel features in geodesics. In this w…

Equatorial periodic orbits and gravitational waveforms in a black hole free of Cauchy horizon
Chao-Hui Wang, Xiang-Cheng Meng, Yu-Peng Zhang +2
In this paper, we study the periodic orbits and gravitational wave radiation in an extreme mass ratio inspiral system, where a stellar-mass object orbits a supermassive black hole…
