报告摘要：
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.
个人简介：
Lijing Shao obtained his PhD degree on Theoretical Physics from the School of Physics at Peking University in 2015. Then he worked as a Junior Scientist for two years in the Max Planck Institute for Gravitational Physics (a.k.a. the Albert Einstein Institute) in Potsdam Germany. After that, Lijing worked as a Scientific Staff for one year in the Max Planck Institute for Radio Astronomy in Bonn Germany. In 2018, he joined the Kavli Institute for Astronomy and Astrophysics at Peking University as a Research Professor / Assistant Professor. He is the group leader of a Max Planck Partner Group at PKU, funded by the Max Planck Society. Lijing’s main research interests include tests of gravity theories, pulsars and neutron stars, gravitational waves, and new physics beyond the standard model of particle physics. He has co-authored the first binary neutron star merger paper (LIGO/Virgo Collaboration, 2017) and the first black hole image paper (Event Horizon Telescope Collaboration, 2019).
