距离倾斜简并限制了紧双星合并引力波参数的估计。虽然简并可以通过包含高阶模式或进动而部分打破，但这些效应在双星中子星中被抑制。在这项工作中，我们实现了一个新的参数化的潮汐效应中的二进制中子星波形，利用二进制的爱的关系，打破了距离倾角简并。二元洛夫关系规定的潮汐变形的中子星星作为其源帧质量的函数，在状态方程不敏感的方式，因此，允许直接测量的红移源。如果假设宇宙学参数是已知的，红移可以转换为光度距离，距离倾斜简并可以因此被打破。我们实现了这种新的方法，研究了一系列的二元中子星观测方案，使用贝叶斯参数估计的合成数据。在第三代探测器时代，对于信噪比范围从6到167的观测，我们预测距离和倾角的90%可信区间将减少，源架分量质量将减少。对于边缘上的系统，我们的方法可以导致适度（）改善测量的距离和倾角的二进制信号噪声比低至10。这个处方可以用来更好地推断源帧质量，因此，细化中子星的人口属性，如它们的最大质量，影响核天体物理。当结合搜索电磁对应的观测，这里提出的工作可以用来把改进的界限喷流从双中子星合并的开口角。
The distance-inclination degeneracy limits gravitational-wave parameter estimation of compact binary mergers. Although the degeneracy can be partially broken by including higher-order modes or precession, these effects are suppressed in binary neutron stars. In this work, we implement a new parametrization of the tidal effects in the binary neutron-star waveform, exploiting the binary Love relations, that breaks the distance-inclination degeneracy. The binary Love relations prescribe the tidal deformability of a neutron star as a function of its source-frame mass in an equation-of-state insensitive way and, thus, allows direct measurement of the redshift of the source. If the cosmological parameters are assumed to be known, the redshift can be converted to a luminosity distance, and the distance-inclination degeneracy can thus be broken. We implement this new approach, studying a range of binary neutron-star observing scenarios using Bayesian parameter estimation on synthetic data. In the era of the third-generation detectors, for observations with signal-to-noise ratios ranging from 6 to 167, we forecast up to andecrease in the 90% credible interval of the distance and inclination and up to andecrease in that of the source-frame component masses. For edge-on systems, our approach can result in moderate () improvement in the measurements of distance and inclination for binaries with a signal-to-noise ratio as low as 10. This prescription can be used to better infer the source-frame masses and, hence, refine population properties of neutron stars, such as their maximum mass, impacting nuclear astrophysics. When combined with the search for electromagnetic counterpart observations, the work presented here can be used to put improved bounds on the opening angle of jets from binary neutron-star mergers.
