Fate of initially bound timelike geodesics in spherical boson stars
Yu-Peng Zhang, Shi-Xian Sun, Yong-Qiang Wang +3
Boson stars are horizonless compact objects and they could possess novel geodesic orbits under the equilibrium assumption, which differ from those in black hole backgrounds. Howeve…
Orbits of photon in Bardeen-boson stars and their frozen states
Long-Xing Huang, Shi-Xian Sun, Yu-Peng Zhang +2
In a recent study [1], the Bardeen-boson star (BBS) model involving a scalar field minimally coupled to Einstein gravity and a Bardeen's nonlinear electromagnetic field was investi…
Bardeen Spacetime with Charged Dirac Field
Shi-Xian Sun, Long-Xing Huang, Zhen-Hua Zhao +1
In this article, we investigate soliton solutions in a system involving a charged Dirac field minimally coupled to Einstein gravity and the Bardeen field. We analyze the impact of…
Bardeen spacetime with charged scalar field
Long-Xing Huang, Shi-Xian Sun, Yong-Qiang Wang
Recently, Ref. \cite{Wang:2023tdz} investigated the model of Einstein-Bardeen theory coupled to a free complex scalar field. The introduction of the scalar field prevents the forma…
