论文摘要
在这项贡献中，我讨论了扰动QCD在研究中子恒星核心问题时提供的效用。我讨论了扰动QCD可以在密度远低于我们可以执行受控计算的密度下限制状态方程的原因。我讨论摄动QCD如何为中子星的核模型提供信息，以及它如何影响状态推理。最后，我讨论了对QCD相图的含义，并认为QCD输入揭示的状态方程中的有趣特征可用于争论在大多数庞大的中子星中存在夸克 - 物质核心。
In this contribution, I discuss the utility that perturbative QCD offers in studying the matter in the cores of neutron stars. I discuss the reasons why perturbative QCD can constrain the equation of state at densities far below the densities where we can perform controlled calculations. I discuss how perturbative QCD can inform nuclear modelling of neutron stars and how it influences equation-of-state inference. And finally, I discuss the implications to the QCD phase diagram and argue that interesting features in the equation of state revealed by the QCD input may be used to argue for the existence of quark-matter cores in most massive neutron stars.
