The inspiral phase of gravitational waves emitted by spinless compact binarysystems is derived through the fourth-and-a-half post-Newtonian (4.5PN) orderbeyond quadrupole radiation, and the leading amplitude mode ($\ell$, m) = (2,2) is obtained at 4PN order. We also provide the radiated flux, as well as thephase in the stationary phase approximation. Rough numerical estimates for thecontribution of each PN order are provided for typical systems observed bycurrent and future gravitational wave detectors.
