论文摘要
费米恩 - 波森星是重力耦合的爱因斯坦 - 克莱因 - 凯琳 - 流动力方程系统的溶液。通过以前的作品中开发的方法，我们对费米昂 - 玻色子星的稳定分析进行了稳定性分析，其中包括其玻感部分中四分之一的自我相互作用。此外，我们描述了自由参数空间的稳定性和不稳定性区域的完整结构，我们认为对于四分之一的自我交互的任何值，我们认为这在质量上都是相同的。还讨论了混合恒星的总质量与它们的一般稳定性之间的关系，以稳定区域内的结构进行讨论。
Fermion-boson stars are solutions of the gravitationally coupled Einstein-Klein-Gordon-Hydrodynamic equations system. By means of methods developed in previous works, we perform a stability analysis of fermion-boson stars that include a quartic self-interaction in their bosonic part. Additionally, we describe the complete structure of the stability and instability regions of the space of free parameters, which we argue is qualitatively the same for any value of the quartic self-interaction. The relationship between the total mass of mixed stars and their general stability is also discussed in terms of the structure identified within the stability region.
