Abstract: We have recently studied gravitational waves from a hierarchical three-body system up to first-order postNewtonian approximation. One of the key players is the so-called Kozai-Lidov oscillation, which causes periodic exchange between eccentricity of inner bindary and relative inclination. In our recent papers, we analyzed dynamics of three-body system which consists of pulsars or black holes, and gravitational waves from such systems. In my talk, I will first explain the results obtained so far by perturbation and/or double-averaging method in the literature and will next discuss our direct simulation for three-body problems and those results.
