论文摘要
对中子恒星的内部外壳特性的详细知识对于解释不同现象（例如脉冲星故障）或中子恒星合并中{\ it r-process}位点的可能性可能很重要。在文献中已经显示，诸如壳校正或配对之类的量子效应可能起着相关作用，以确定中子恒星内皮的组成。在本文中，我们使用有限的gogny相互作用构建内皮状态的方程，其中平均场和配对场是通过相同相互作用计算的。我们已经使用了分别使用Strutinsky积分方法和BCS近似计算的半经典变化Wigner-Kirkwood方法和壳和配对校正。我们的结果与文献中一些流行模型的结果进行了比较。我们报告了用D1M* Gogny力计算的内皮和核心状态的统一方程，该方程是专门用于天体物理计算的。
The detailed knowledge of the inner crust properties of neutron stars might be important to explain different phenomena such as pulsar glitches or the possibility of an {\it r-process} site in neutron star mergers. It has been shown in the literature that quantal effects like shell correction or pairing may play a relevant role to determine the composition of the inner crust of the neutron star. In this paper we construct the equation of state of the inner crust using the finite-range Gogny interactions, where the mean field and the pairing field are calculated with same interaction. We have used the semiclassical Variational Wigner-Kirkwood method along with shell and pairing corrections calculated with the Strutinsky integral method and the BCS approximation, respectively. Our results are compared with those of some popular models from the literature. We report a unified equation of state of the inner crust and core computed with the D1M* Gogny force, which was specifically fabricated for astrophysical calculations.
