Description

Post-Newtonian (PN) calculations constitute a crucial ingredient to build the
waveform models for compact binaries that are used in the data analysis of the
current (and future) gravitational-wave interferometers. For the resulting
templates to be faithful, the overlap of the PN polarisations with their
numerical counterparts must be made as high as possible. This requires to
obtain the orbital phase analytically at the 4PN order at least. We shall
describe the current status of this computation, focusing on the most recent
progress. We shall also discuss the implementation of the tidal effects at the
2PN order, relevant in the case where the companions are neutron stars.
