报告摘要：
The accumulation of experimental data for direct detections of gravitational waves (GWs) calls for increasingly precise theoretical predictions. The binary inspiral of compact objects including black holes and neutron stars, which generates the major part of the GW signals, needs to be studied analytically in the post-Newtonian (PN) regime, i.e. in the weak field, non-relativistic limit. The effective field theories (EFTs), originally developed for particle physics, turn out to be powerful in studying the classical physics of the GW phenomena as well. In particular, the EFT of spinning gravitating objects has been consistently producing state-of-the-art theoretical predictions for spin effects in GW physics. I will present the most recent progress in this direction, including both formal theoretical developments, as well as the completion of the fifth-PN description of binary inspiral for the first time.
