论文摘要
从有限范围的gogny力和动量依赖性相互作用获得的一组状态方程用于研究近期从二进制中子恒星合并GW170817事件中对重力波的观察。对于这组互动，我们计算了中子星潮汐变形（与第二个爱情号码有关），质量 - 拉迪乌斯图和惯性〜（$ i $）的力矩。 $ i $ - 爱的关系已验证。我们还发现，在饱和密度下，典型中子恒星，半径和核对称能的衍生物的潮汐变形性之间存在很强的相关性。大多数获得的结果位于从GW170817检测中提取的潮汐变形的约束之内。
A set of equations of state obtained from finite-range Gogny forces and momentum-dependent interactions is used to investigate the recent observation of gravitational waves from the binary neutron star merger GW170817 event. For this set of interactions, we have calculated the neutron star tidal deformabilities (related to the second Love number), the mass-radius diagram, and the moment of inertia~($I$). The $I$-Love relation has been verified. We also have found strong correlations among the tidal deformability of the canonical neutron star, its radius, and the derivatives of the nuclear symmetry energy at the saturation density. Most of the obtained results are located within the constraints of the tidal deformabilities extracted from the GW170817 detection.
