Light Rings, Accretion Disks and Shadows of Hayward Boson Stars
Zhen-Hua Zhao, Yi-Ning Gu, Shu-Cong Liu +2
In this paper, we investigate the Einstein-Hayward gravity coupled to a complex scalar field without self-interaction. Using numerical methods, we construct a class of Hayward boso…

Frozen solitonic Hayward-boson stars in Anti-de Sitter Spacetime
Shu-Cong Liu, Yong-Qiang Wang, Zhen-Hua Zhao
We construct solitonic Hayward-boson stars (SHBSs) in Anti-de Sitter (AdS) spacetime, which consists of the Einstein-Hayward model and a complex scalar field with a soliton potenti…

Non-Topological Soliton Bardeen Boson Stars and Their Frozen States
Zhen-Hua Zhao, Yi-Ning Gu, Shu-Cong Liu +2
We investigate a Bardeen model coupling Einstein gravity with nonlinear electromagnetic fields and non-topological soliton complex scalar fields, governed by the magnetic charge $\…
