致密星中的团簇形成:相对论模型与Skyrme模型

Cluster formation in compact stars: relativistic versus Skyrme models

Camille Ducoin, Constança Providência, Alexandro M. Santos, Lucilia Brito, Philippe Chomaz

摘要:

我们提出了各种性质的核和致密星物质,比较预测从两种唯象的方法:相对论模型(包括常数和密度依赖耦合)和非相对论Skyrme型相互作用。我们主要集中在液-气不稳定性,发生在欠饱和密度,导致分解的均匀物质成一个集群相。这种研究与中子星壳(零温度)和超新星动力学(有限温度)的描述有关。

英文摘要:

We present various properties of nuclear and compact-star matter, comparing the predictions from two kinds of phenomenological approaches: relativistic models (both with constant and density-dependent couplings) and non-relativistic Skyrme-type interactions. We mainly focus on the liquid-gas instabilities that occur at sub-saturation densities, leading to the decomposition of the homogeneous matter into a clusterized phase. Such study is related to the description of neutron-star crust (at zero temperature) and of supernova dynamics (at finite temperature).
