Nucleon-nucleon short-range correlations (SRCs) are inevitable consequences of realistic nucleon-nucleon interactions. The corresponding SRC pairs, characterized by high relative momenta, have been verified experimentally to be important in finite nuclei. In this work, we study the impacts of nucleon-nucleon SRCs on the physical properties of neutron stars. Considering the small center-of-mass momenta of SRC pairs, new nucleon momentum distributions with high-momentum tails (HMTs) are proposed by extrapolating well-established experimental results of SRCs in finite nuclei to neutron star matter. HMTs with different shapes are adopted to estimate theoretical uncertainties. It is found that nucleon-nucleon SRCs generally stiffen the equation of state of neutron star matter and increase the maximum mass of neutron stars.

核子-核子短程相关性（SRC）是现实的核子-核子相互作用的必然结果。以高相对动量为特征的相应SRC对已通过实验证明在有限原子核中很重要。在这项工作中，我们研究了核子-核子SRC对中子星物理性质的影响。考虑到SRC对的小质心动量，通过将有限核中已确立的SRC实验结果外推到中子星体，提出了具有高动量尾部（HMT）的新核子动量分布。采用不同形状的HMT来估计理论不确定性。已发现，核子-核子SRC通常会使中子星物质的状态方程变硬，并增加中子星的最大质量。
