Linear stability matrix and Lyapunov exponents for stationary spacetime
Xu Ye, Shao-Wen Wei
Lyapunov exponents characterize the average rate at which nearby trajectories in phase space converge or diverge and therefore provide a useful criterion for dynamical stability. I…
Gravity/thermodynamics correspondence via black hole shadows
Shao-Wen Wei, Yu-Xiao Liu
The shadow of a black hole serves as a pristine window into the strong-gravity regime, with cuspy feature emerging as a smoking-gun signature of physics beyond the Kerr paradigm. I…
Interior geometry of black holes as a probe of first-order phase transition
Zi-Qiang Zhao, Zhang-Yu Nie, Shao-Wen Wei +2
Traditional diagnostics of black hole phase transitions rely on thermodynamic quantities defined at the event horizon or asymptotic boundary. Here, we demonstrate that the near-sin…
Magnetic field effects on spherical orbit in Kerr-Bertotti-Robinson spacetime: constraints from jet precession of M87*
Chao-Hui Wang, Xiang-Cheng Meng, Shao-Wen Wei
The recently reported precession period of about years of the M87* jet provides a sensitive probe of strong field gravity and the electromagnetic environment in the immedia…
Enhanced energy extraction via magnetic reconnection in Kerr-AdS spacetime
Bo Zhao, Chao-Hui Wang, Shao-Wen Wei
In this paper, we study the energy extraction from Kerr-AdS black holes following the magnetic reconnection process. The parameter space regions that satisfy the energy extraction…
Effects of magnetic fields on spinning test particles orbiting Kerr-Bertotti-Robinson black holes
Yu-Kun Zhang, Shao-Wen Wei
In this paper, we study the kinematic effects of spinning test particles orbiting the Kerr-Bertotti-Robinson black hole. Employing with the Mathisson-Papapetrou-Dixon equations, we…
A new type of multi-branch periodic orbits in dyonic black holes
Chao-Hui Wang, Yu-Peng Zhang, Tao Zhu +1
We investigate bound timelike periodic orbits in dyonic black hole spacetimes arising from quasi-topological electromagnetism. By varying the coupling parameter , we show that…
Characteristic precessions of spherical orbit around a rotating braneworld black hole
Hui-Min Wang, Kai Liao, Shao-Wen Wei
We study the orbital dynamics and relativistic precession effects in the spacetime of rotating braneworld black holes within the Randall-Sundrum framework. For test particles on sp…
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…
Imprints of black hole charge on the precessing jet nozzle of M87*
Xiang-Cheng Meng, Chao-Hui Wang, Shao-Wen Wei
The observed jet precession period of approximately 11 years for M87* strongly suggests the presence of a supermassive rotating black hole with a tilted accretion disk at the cente…
Novel topological phenomena of timelike circular orbits for charged test particles
Xu Ye, Shao-Wen Wei
The topological approach has recently been successfully employed to investigate timelike circular orbits for massive neutral test particles. The observed vanishing topological numb…
