论文摘要
在本文中,我们构建\ textit {dirac-boson stars}(DBSS)模型,该模型由标量字段和两个迪拉克字段组成。标量场和两个狄拉克场处于基态。我们考虑分别为同步频率$ \tildeΩ$和非同步频率$ \tildeΩ_d$ case的DBSS的解决方案家族。当Dirac质量$ \tildeμ_d$和标量场频率$ \tildeΩ_s$在某些特定范围内采用时,我们会发现几种不同的解决方案。相比之下,在多矿石玻色子恒星的先前研究中没有发现类似的情况。此外,我们讨论了DBSS的每种溶液家族的特征,并介绍DBSS的ADM质量$ m $与同步频率$ \tildeΩ$或非同步频率$ \tildeΩ_d$之间的关系。最后,我们计算了DBSS的绑定能$ e_b $,并研究$ e_b $与同步频率$ \tildeΩ$或非同步频率$ \tildeΩ_d$的关系。
In this paper, we construct \textit{Dirac-boson stars} (DBSs) model composed of a scalar field and two Dirac fields. The scalar field and both Dirac fields are in the ground state. We consider the solution families of the DBSs for the synchronized frequency $\tildeω$ and the nonsynchronized frequency $\tildeω_D$ cases, respectively. We find several different solutions when the Dirac mass $\tildeμ_D$ and scalar field frequency $\tildeω_S$ are taken in some particular ranges. In contrast, no similar case has been found in previous studies of multistate boson stars. Moreover, we discuss the characteristics of each type of solution family of the DBSs and present the relationship between the ADM mass $M$ of the DBSs and the synchronized frequency $\tildeω$ or the nonsynchronized frequency $\tildeω_D$. Finally, we calculate the binding energy $E_B$ of the DBSs and investigate the relationship of $E_B$ with the synchronized frequency $\tildeω$ or the nonsynchronized frequency $\tildeω_D$.
