论文摘要
预计中性恒星内部外壳的底部，有望存在核的异国情调的非球形构型。我们研究了在可压缩的液体滴射模型中，这些构型在催化的中子恒星中的特性，具有强大的核能均显示出了属性。进行不确定性，进行了贝叶斯分析，将核物理学实验的信息和手性扰动理论计算与天体物理观测结合在一起。
Exotic non-spherical configurations of nuclei, known as ``pasta" phases, are expected to be present at the bottom of the inner crust of a neutron star. We study the properties of these configurations in catalyzed neutron stars within a compressible liquid-drop model approach, with surface parameters optimized to reproduce experimental nuclear masses. Our results show that the properties of the pasta phases exhibit strong model dependence. To estimate the model uncertainties, a Bayesian analysis is performed, combining information from nuclear physics experiments and chiral perturbation theoretical calculations with astrophysical observations. The inferred posterior distributions are discussed, with particular focus on the effect of the low-density energy functional on the predictions.
