带电魅力星

Charged charm stars

V. P. Goncalves, L. Lazzari

摘要:

在MIT袋模型框架下研究了具有净电荷的粲星的一般性质和稳定性。我们考虑两种不同的模型的电荷分布和demostate,都意味着恒星配置较大的质量,并满足平衡条件。研究了径向振动的动力学稳定性。我们的研究结果表明,本征频率被修改的净电荷的存在下,但不稳定性,先前证明的电中性的情况下,也存在于带电的魅力星。

英文摘要:

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.
