DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CENTRA/18/">
 Post-Newtonian Kozai-Lidov mechanism and Gravitational waves from hierarch
 ical triple systems</a>\nby Hirotada Okawa (Waseda Institute for Advanced 
 Study) as part of CENTRA Seminar\n\n\nAbstract\nWe have recently studied g
 ravitational waves from a hierarchical three-body system up to first-order
  postNewtonian approximation. One of the key players is the so-called Koza
 i-Lidov oscillation\, which causes periodic exchange between eccentricity 
 of inner bindary and relative inclination. In our recent papers\, we analy
 zed dynamics of three-body system which consists of pulsars or black holes
 \, and gravitational waves from such systems. In my talk\, I will first ex
 plain the results obtained so far by perturbation and/or double-averaging 
 method in the literature and will next discuss our direct simulation for t
 hree-body problems and those results.\n
