Polarization Images of Neutron Stars Illuminated by a Thin Accretion Disk: A Comparison with Black Holes
Dan-Dan Feng, Guo-Ping Li, Chen-Yu Yang +1
We investigate linear polarization images of static, spherically symmetric neutron stars illuminated by a geometrically and optically thin accretion disk. Neutron star equilibrium…
Energy Extraction via Magnetic Reconnection from Rotating ModMax Black Holes
Shi-Hao Wang, Ke-Jian He, Guo-Ping Li +1
Magnetic reconnection has been widely recognized as an important mechanism for extracting energy from rapidly rotating black holes. We find that magnetic reconnection can also effi…
Chaos bound violation by spinning particles in Gauss-Bonnet-AdS black holes
Xiaowei Li, Mengxuan Wu, Guoping Li
In this work, we investigate the violation of the chaos bound for spinning test particles in Gauss-Bonnet anti-de Sitter spacetime, focusing on the regulatory roles of the Gauss-Bo…
Particle decay and energy conservation in the Kerr-Newman black hole
Bing-Bing Chen, Guo-Ping Li, Ke Wang +1
In this paper, we study the decay of a particle in Kerr--Newman spacetime. Both theoretical analysis and numerical simulations show that when a particle splits in Kerr--Newman spac…
Horizon-scale intensity and polarization images of rotating Konoplya-Zhidenko black holes with thick accretion flows
Bing-Bing Chen, Chen-Yu Yang, Guo-Ping Li +1
We investigate the shadow and polarization images of a Konoplya-Zhidenko rotating non-Kerr black hole surrounded by a geometrically thick and optically thin accretion flow. The acc…
Gravitational lensing and observational features of a dynamic black hole
Ke-Jian He, Guo-Ping Li, Li-Fang Li +1
In this work, we investigate the gravitational lensing effects and the dynamic evolution of the shadow of Vaidya black holes by employing backward ray-tracing techniques. Within th…
