« Gravitational radiation from compact binary star systems » |
Luc Blanchet |
To be observed and analyzed by the gravitational wave detectors LIGO and VIRGO on ground and LISA in space, inspiralling compact binaries (binary star systems composed of neutron stars and/or black holes) require high-accuracy templates predicted by general relativity. These very relativistic systems are ideally suited for application of a high-order post-Newtonian gravitational wave generation formalism. In this talk, after general introduction and motivation, we shall review the current state of the art on post-Newtonian methods as applied to the motion and gravitational radiation of compact binary systems. We shall then present some recent work on the comparison between the post-Newtonian approximation and black hole perturbation theory as applied to compact binary systems with very small mass ratio. Finally we shall review the recent post-Newtonian calculations of the gravitational recoil of the black hole formed by coalescence of compact binary systems. |
