论文摘要
第三代重力波(GW)观测值,例如爱因斯坦望远镜(ET)和宇宙资源管理器(CE)将是理想的仪器,可以通过在经历二元合并时发出的GW探测中子恒星的结构。在这项工作中,我们可以通过观察数十种二元中子星凝聚力的观察到具有数百个信噪比的比率,从而预测ET特别能够使我们能够使我们能够重建状态的中子星方程。我们将自己限制在可以从Inspiral中提取的信息,其中包括潮汐效应和可能的R模式共振。在治疗后者时,我们超越了牛顿近似,引入和利用新的普遍关系。我们发现,观察共振的R模式的能力将对使用ET的状态测量值的中子星方程产生明显影响。
Third-generation gravitational wave (GW) observatories such as Einstein Telescope (ET) and Cosmic Explorer (CE) will be ideal instruments to probe the structure of neutron stars through the GWs they emit when undergoing binary coalescence. In this work we make predictions about how well ET in particular will enable us to reconstruct the neutron star equation of state through observations of tens of binary neutron star coalescences with signal-to-noise ratios in the hundreds. We restrict ourselves to information that can be extracted from the inspiral, which includes tidal effects and possibly r-mode resonances. In treating the latter we go beyond the Newtonian approximation, introducing and utilizing new universal relations. We find that the ability to observe resonant r-modes would have a noticeable impact on neutron star equation of state measurements with ET.
