| GR has very specific predictions for the gravitational waveforms from inspiralling compact binaries obtained using the PN approximation. We investigate the extent to which the measurement of the PN coefficients could be used to test GR and to put bounds on a class of theories which differ from it in a parametrized sense. We demonstrate this possibility with the Advanced LIGO and Einstein Telescope (ET), by employing the non-spinning waveform models for compact binaries which is 3.5PN-accurate in phase and 3PN in amplitude. Advanced LIGO can test the theory at 1.5PN and thus the leading tail term. ET can test the consistency between the various PN coefficients in the GW phasing over the mass range of 11-44 solar masses. |
