摘要:

在本文中,我们构建了一个包含复标量场和Proca场的混合玻色子星模型。标量场处于基态,而Proca场处于第一激发态。我们对模型进行数值求解,并通过考虑同步和非同步两种情况,得到了不同共存态的解族。通过考察ADM质量与同步频率$\ ildeω$或非同步频率$\ ildeω_P$之间的关系,我们识别出混合玻色子星的几种解族类型。除了在两端分别与标量场和Proca场相交的解之外,还存在几种多分支共存态解。我们详细分析和讨论了各种解的特性。我们计算了混合Proca-玻色子星的结合能$E$,并给出了$E$与同步频率$\ ildeω$及非同步频率$\ ildeω_P$之间的关系。此外,我们从上述分析中得到了相应混合星解族的稳定性。

英文摘要:

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 the first excited state. We numerically solve the model and obtain solution families of different coexisting states by considering both synchronized and nonsynchronized cases. By examining the relation between ADM mass and synchronized frequency $\tildeω$ or nonsynchronized frequency $\tildeω_P$, we identify several types of solution families for the hybrid boson stars. In addition to solutions that intersect the scalar field and the Proca field at each end, there are also several types of multi-branch coexisting state solutions. The characteristics of various solutions are analyzed and discussed in detail. We calculate the binding energy $E$ of the hybrid Proca-boson stars and provide the relationship between $E$ and both synchronized frequency $\tildeω$ and nonsynchronized frequency $\tildeω_P$. Furthermore, we obtain the stability of the corresponding hybrid star solution families from these analyses above.
