摘要：
中子星核心的状态方程可以通过要求其与高密度下的微扰量子色动力学（QCD）计算保持一致连接来加以约束。QCD输入的约束能力取决于来自缺失高阶项、非物理重整化标度的选择以及执行QCD计算的参考密度的不确定性。在贝叶斯方法框架内，我们讨论了微扰QCD级数的收敛性，量化了其在高密度下的不确定性，并提出了一个系统地将这些不确定性向下传递至中子星密度的框架。我们发现，QCD输入对中子星推断的影响对不确定性估计中做出的各种非物理选择不敏感。
英文摘要：
The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input depends on uncertainties from missing higher-order terms, the choice of the unphysical renormalization scale, and the reference density where QCD calculations are performed. Within a Bayesian approach, we discuss the convergence of the perturbative QCD series, quantify its uncertainties at high densities, and present a framework to systematically propagate the uncertainties down to neutron-star densities. We find that the effect of the QCD input on the neutron-star inference is insensitive to the various unphysical choices made in the uncertainty estimation.
