Chains of rotating boson stars with quartic or sextic self-interaction
Hao-Ran Sun, Jing-Kang Bin, Li Zhao
This paper investigates chains of rotating boson stars (BSs) within Einstein gravity coupled to a complex scalar field. The model incorporates quartic or sextic self-interactions i…
Bardeen-Dirac Stars in AdS Spacetime
Xiao-Yu Zhang, Li Zhao, Yong-Qiang Wang
In this paper, we construct a static spherical symmetric Bardeen-Dirac Stars (BDSs) in the four-dimensional Anti-de Sitter (AdS) spacetime, which consists of the electromagnetic fi…
Dirac stars in Anti-de Sitter Spacetime
Xiao-Yu Zhang, Li-Zhao, Yong-Qiang Wang
In this paper, we construct the Dirac stars model composed of two Dirac fields and Einstein gravity in four-dimensional Anti-de Sitter spacetime. We consider the Dirac stars with f…
Tidal Love numbers of Axion stars
Jun-Ru Chen, Shi-Xian Sun, Long-Xing Huang +1
We investigate the tidal deformability of spherically symmetric axion stars on the stable branches, including the Newtonian and relativistic branches. The results suggest that on t…
