核心坍缩超新星物质:轻团、pasta相和相变

Core-collapse supernova matter: light clusters, pasta phase and phase transitions

Helena Pais, Constança Providência, William G. Newton, Jirina R. Stone

摘要:

在相对论平均场模型中研究了核心坍缩超新星物质(有限温度和固定质子分数)中的pasta相。两种不同的计算方法用于比较,分别是双相费米(TF)近似和共存相(CP)近似。还研究了在核物质中包括轻团簇的影响以及在意大利面配置和均匀物质之间发生转变的密度。最后,与有限温度Skyrme-Hartree-Fock计算进行了比较。

英文摘要:

The pasta phase in core-collapse supernova matter (finite temperatures and fixed proton fractions) is studied within relativistic mean field models. Two different calculations are used for comparison, the Thomas-Fermi (TF) and the Coexisting Phases (CP) approximations. The effects of including light clusters in nuclear matter and the densities at which the transitions between pasta configurations and to uniform matter occur are also investigated. Finally, a comparison with a finite temperature Skyrme-Hartree-Fock calculation is drawn.
