報告摘要：

Neutron stars are special in the field of gravitational waves and are crucial for the fundamental physics. The first indirect detection of gravitational waves came from the Hulse-Taylor binary pulsar, which is composed of two neutron stars. The binary pulsar not only earned the Nobel prize in 1993 to Hulse & Taylor, but also solidified the case for constructing the LIGO/Virgo/KAGRA gravitational-wave detectors. In 2017, the observation of a binary neutron star merger, the so-called GW170817, marks the opening of multi-messenger astrophysics and starts a totally new era. I will talk about neutron stars in gravitational-wave observations, and their unique contribution to tests of gravity theories, as well as to probe the equation of state for supranuclear matters which is ultimately related to the nonperturbative QCD.
