论文摘要
在MIT袋型号框架内，对具有净电荷的魅力恒星的一般特性和稳定性进行了研究。我们考虑了两种不同的电荷分布和脱位模型，这两个模型都暗示具有较大质量的出色配置，并且满足了平衡条件。研究了针对径向振荡的动力稳定性。我们的结果表明，特征频率通过净电荷的存在来改变，但是在带电的魅力恒星中也存在先前证明的电气中的不稳定。
The study of the general properties and stability of charm stars with a net electric charge is performed within the MIT bag model framework. We consider two different models for the electric charge distribution and demostrate that both imply stellar configurations with larger masses and that satisfy the equilibrium condition. The dynamical stability against radial oscillations is investigated. Our results demonstrate that the eigenfrequencies are modified by the presence of a net electric charge, but the instability, previously demonstrated for the electrically neutral case, is also present in charged charm stars.
