Post-Newtonian dynamics of binaries and its relevance to relativistic astrophysics — •Achamveedu Gopakumar — Theoretisch-Physikalisches Institut, FSU , Max-Wien-Platz 1, 07743 Jena, Germany

The dynamics of compact binaries in post-Newtonian (PN) approximation is recently determined, both in near-zone orbital dynamics and in far-zone flux computations, to {∖em third and half} PN order. I describe briefly importance and implications of these results for i) gravitational wave astronomy, realizable with Laser Interferometers and Square Kilometre Array, ii) timing of binary pulsars, iii) numerical relativity involving compact binaries, iv) N-body simulations to model globular clusters and supermassive black hole mergers and v) infra-red observations of stars orbiting our galactic center.
