论文摘要
基于[1]中提出的GW色散关系，我们研究了中子星中通过超流体（SF）对重力波（GW）的可能反射，提供了其高密度和无耗散特性。在这种情况下，提出了一项实验建议，以通过GW检测来探测中子星中的预期SF。考虑了两种类型的二进制系统，即中子星形黑洞和二元中子星系，其引力场条件较弱。发现了由GW反射引起的总信号的不可忽略的调制，从而有助于与原始正弦信号区分的振幅和相变。此外，我们表明，宇宙资源管理器和爱因斯坦望远镜以$ 100 \，\ mbox {mpc} $检测到此类调制。这些信号的识别可以证明中子恒星中长期以来的SF存在以及外来超流体引起的GW反射。
Based on the GW dispersion relation raised in [1], we investigate the possible reflection of gravitational wave (GW) by superfluidity (SF) in the neutron star, provided its high density and dissipationless properties. Following this scenario, an experimental proposal is raised to probe the expected SF in neutron star by means of GW detection. Two types of binary systems are considered, neutron star-black hole and binary neutron star systems, with weak gravitational field condition imposed. Non-negligible modulation on the total signal caused by the GW reflection is found, which contributes amplitude and phase variations distinguishable from the primitive sine signal. Furthermore, we show that it is possible for such modulations to be detected by the Cosmic Explorer and Einstein Telescope at $100\,\mbox{Mpc}$. Identification of those signals can evince the existence of the long-sought SF in neutron stars as well as the exotic superfluidity-induced GW reflection.
