论文摘要
我们解决了在广义天际模型中描述的中子星核中带电的kaon冷凝物出现的可能性。我们对奇怪的自由度的处理是基于Callan和Klebanov的界面方法，该方法允许在$ s $ wave Kaon冷凝物中获得中等内部的有效潜力。我们预测KAON凝结在一定阈值密度下的发作 - 其值取决于模型的参数，并且在1.5到2.5倍的饱和密度之间 - 并获得KAON冷凝相中密集物质的粒子分数和状态方程。最后，我们讨论了这种冷凝物对带有kaon凝结核的中子恒星的质量 - 拉迪乌斯曲线的影响。
We address the possibility of the appearance of a charged kaon condensate in neutron star cores described within a generalized Skyrme model. Our treatment of strange degrees of freedom is based on the Bound State Approach by Callan and Klebanov, which allows to obtain an in-medium effective potential for the $s$-wave kaon condensate. We predict the onset of kaon condensation at a certain threshold density - whose value depends on the parameters of the model, and ranges between 1.5 and 2.5 times saturation density -, and obtain both the particle fractions and equation of state for dense matter in the kaon condensed phase. Finally, we discuss the effect of such condensates on the mass-radius curves and other observable properties of neutron stars with kaon condensed cores.
