论文摘要
重力波信号GW170817的观察与二进制中子星系的灵感发射一致，提供了有关参与恒星的潮汐变形的信息。可以利用可用的数据来限制致密物质状态的方程，并阐明描述显微镜水平核动力学的基础模型。在本文中，我们将实验结果与不同理论模型的预测进行了比较，该预测基于非相对论核多体型理论，相对论的现场理论形式主义以及受观察到的核特性约束的更现象学方法。尽管可用数据的精度无法解析模型的退化，但我们的分析显示了对不同状态方程所预测的恒星紧凑性的明显敏感性，事实证明，这种状态对核子 - 核核势的相对论增强校正的影响很大。
The observation of the gravitational wave signal GW170817, consistent with emission from the inspiral of a binary neutron-star system, provided information on the tidal deformation of the participating stars. The available data may be exploited to constrain the equation of state of densenuclear matter, as well as to shed light on the underlying models describing nuclear dynamics at microscopic level. In this paper we compare the experimental results to the predictions of different theoretical models, based on non relativistic nuclear many-body theory, the relativistic field-theoretical formalism, and a more phenomenological approach constrained by observed nuclear properties. While the precision of the available data does not allow to resolve the degeneracy of the models, our analysis shows a distinct sensitivity to the star compactness predicted by the different equations of state, which turns out to be significantly affected by relativistic boost corrections to the nucleon-nucleon potential.
