论文摘要
{\ it背景。}我们研究了中子星观测与原子核的性质之间的可能相关性。特别是，我们探讨了1.4太阳质量中子星的潮汐变形性，$ m_ {1.4} $以及中子皮肤的厚度$ {^{48}} $ ca和$ {^{^{208}} $ pb与恒星半径和对称能量的刚度有关。 {\ it方法。}我们基于现象学模型（Skyrme，nlwm，ddm）和{\ it ab-initio}理论方法（BBG，Dirac-Brueckner，变量，量子Monte Carlo），基于现象学模型（Skyrme，nlwm，ddm）和{\ it ab-initio}研究一组核方程。 {\ IT结果。}我们发现潮汐变形性与NS半径之间的强相关性，而与对称能量的刚度确实存在较弱的相关性。关于中子皮肤厚度，弱相关性既出现在对称能量的刚度，又出现$ m_ {1.4} $的半径。 {\ IT结论。} $ M_ {1.4} $的潮汐变形性和原子核的中子皮肤厚度表现出与核和天体物理可观察物的一定程度的相关性，但是这取决于所采用的EOS的整体。
{\it Background.} We investigate possible correlations between neutron star observables and properties of atomic nuclei. Particularly, we explore how the tidal deformability of a 1.4 solar mass neutron star, $M_{1.4}$, and the neutron skin thickness of ${^{48}}$Ca and ${^{208}}$Pb are related to the stellar radius and the stiffness of the symmetry energy. {\it Methods.} We examine a large set of nuclear equations of state based on phenomenological models (Skyrme, NLWM, DDM) and {\it ab-initio} theoretical methods (BBG, Dirac-Brueckner, Variational, Quantum Monte Carlo). {\it Results.} We find strong correlations between tidal deformability and NS radius, whereas a weaker correlation does exist with the stiffness of the symmetry energy. Regarding the neutron skin thickness, weak correlations appear both with the stiffness of the symmetry energy, and the radius of a $M_{1.4}$. {\it Conclusion.} The tidal deformability of a $M_{1.4}$ and the neutron-skin thickness of atomic nuclei show some degree of correlation with nuclear and astrophysical observables, which however depends on the ensemble of adopted EoS.
