根据双中子星合并GW 170817期间进行的新测量，我们分析了矢量-等矢量介子相互作用在中子星内部致密物质中所发挥的作用。这些涉及到从引力波和电磁观测中测量潮汐变形能力。我们的研究包括三个不同的状态方程，包含不同的物理假设和物质组成，即NL 3家族，MBF和CMF模型。其他相关的数量/关系分析的中子物质压力，对称性能量斜率，恒星质量和半径，和Urca过程的恒星冷却阈值。
We analyze the role played by vector-isovector meson interaction in dense matter present in the interior of neutron stars in the light of new measurements made during the double neutron-star merger GW170817. These concern measurements of tidal deformability from gravitational waves and electromagnetic observations. Our study includes three different equations of state that contain different physical assumptions and matter compositions, namely the NL3 family, MBF, and CMF models. Other related quantities/relations analyzed are the neutron matter pressure, symmetry energy slope, stellar masses and radii, and Urca process threshold for stellar cooling.
