Excited Dirac stars with higher azimuthal harmonic index
Long-Xing Huang, Shi-Xian Sun, Rong Zhang +2
In this paper, we investigate the properties of the first excited state Dirac stars (DSs) with higher azimuthal harmonic index (specifically, the azimuthal harmonic indexes =…

Dirac-Proca stars
Tian-Xiang Ma, Chen Liang, Ji-Rong Ren +1
We consider a model consists of the Einstein gravity in four-dimensional spacetime, a Proca field and two Dirac fields through minimum coupling. By numerically solving this model,…

Hybrid Proca-boson stars
Tian-Xiang Ma, Chen Liang, Jie Yang +1
In this paper, we construct a hybrid boson star model that contains a complex scalar field and a Proca field. The scalar field is in the ground state, while the Proca field is in t…
