标题： Determining the equation of state of neutron stars with Einstein Telescope using tidal effects and r-mode excitations from a population of binary inspirals

摘要： 第三代引力波（GW）观测设施，如爱因斯坦望远镜（ET）和宇宙探索者（CE），将成为通过它们在双星合并时发出的GW来探测中子星结构的理想工具。 在这项工作中，我们预测ET尤其能够通过观察数百个信噪比的双中子星合并来重建中子星状态方程。 我们仅限于从旋进阶段提取的信息，这包括潮汐效应和可能的r模共振。 在处理后者时，我们超越了牛顿近似，引入并利用了新的普遍关系。 我们发现，观察共振r模将对ET中的中子星状态方程测量产生显著影响。 显示英文摘要

摘要： 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.
