Dynamical instabilities for model with point-coupling interactions: Vlasov formalism method
摘要:
采用Vlasov方法,在点耦合作用的RMF理论下,研究了对称能密度依赖性对冷、暖中子星动力学不稳定性和壳核相变的影响.温度和中微子捕获的作用也被考虑。讨论了蒸馏效应、壳核转变密度和压力、团簇大小和生长速率。结果表明,对称能的斜率、温度和中微子俘获效应都有明显的影响。
英文摘要:
We explore the effects of the density dependence of symmetry energy on the dynamical instabilities and crust-core phase transition in the cold and warm neutron stars in the RMF theory with point-coupling interactions using the Vlasov approach. The role of the temperature and neutrino trapping has also been considered. The distillation effect, crust-core transition density and pressure, the cluster size and growth rates have been discussed. The present work shows that the slope of symmetry energy, temperature, and neutrino trapping have obvious effects.
