Kerr black hole shadows from the axion-photon coupling
Songbai Chen, Jiliang Jing
We have investigated the motion for photons in the Kerr black hole spacetime under the axion-photon coupling. The birefringence phenomena arising from the axion-photon coupling can…
Chaotic motion of scalar particle coupling to Chern-Simons invariant in the stationary axisymmetric Einstein-Maxwell dilaton black hole spacetime
Lina Zhang, Songbai Chen, Qiyuan Pan +1
We investigate the motion of a test scalar particle coupling to the Chern-Simons (CS) invariant in the background of a stationary axisymmetric black hole in the Einstein-Maxwell-Di…
Thick accretion disk configurations around a compact object in the brane-world scenario
Yunzhu Wei, Songbai Chen, Jiliang Jing
We have studied equipotential surfaces of a thick accretion disk around a Casadio-Fabbri-Mazzacurati (CFM) compact object in the brane-world scenario, which owns a mass parameter t…
Kerr black hole shadows cast by extraordinary light rays with Weyl corrections
Songbai Chen, Jiliang Jing
We investigate the equation of motion for photons with Weyl corrections in a Kerr black hole spacetime in a small coupling case. Our results show that Weyl corrections yield phenom…
The ring-shaped shadow of rotating naked singularity with a complete photon sphere
Mingzhi Wang, Guanghai Guo, Pengfei Yan +2
We investigate the shadows of Konoplya-Zhidenko naked singularity. In the spacetime of Konoplya-Zhidenko naked singularity, not only can unstable retrograde light ring (LR) exist,…
Geometrically thick equilibrium tori around a dyonic black hole with quasi-topological electromagnetism
Xuan Zhou, Songbai Chen, Jiliang Jing
We study geometrically thick and non-self gravitating equilibrium tori orbiting a static spherically symmetric dyonic black hole with quasi-topological electromagnetism. Our result…
