论文摘要
从理论计算中预测了连接潮汐变形性和单个中子恒星的四极力矩的准宇宙关系，但尚未通过实验测量。但是，这种关系是在重力波解释过程中采用的，因此对真实数据的解释有直接影响。在这项工作中，我们研究了如何从与二元中子星凝聚的重力波信号中测试和测量准宇宙关系。我们研究了$ 120 $二进制中子星系的人群，并发现，如果观察到的中子恒星高度旋转，则高级Ligo和Advanced Pirgo处于设计敏感性时可能会发现预测关系的偏差。将来，第三代（3G）探测器的网络甚至可以允许测量准全面关系。因此，概述的方法提供了一般相对论和核物理预测的新测试。
Quasi-universal relations connecting the tidal deformability and the quadrupole moment of individual neutron stars are predicted by theoretical computations, but have not been measured experimentally. However, such relations are employed during the interpretation of gravitational waves and, therefore, have a direct impact on the interpretation of real data. In this work, we study how quasi-universal relations can be tested and measured from gravitational wave signals connected to binary neutron star coalescences. We study a population of $120$ binary neutron star systems and find that Advanced LIGO and Advanced Virgo at design sensitivity could find possible deviations of predicted relations if the observed neutron stars are highly spinning. In the future, a network of third generation (3G) detectors will be able to even allow a measurement of quasi-universal relations. Thus, the outlined approach provides a new test of general relativity and nuclear physics predictions.
