We calculate the 2 post-Newtonian correction to the radiation reaction acceleration for non-spinning binary systems, which amounts to the 4.5 post-Newtonian correction to Newtonian acceleration. The calculation is carried out completely using the effective field theory approach. The center-of-mass corrections to the results are complicated and are discussed in detail. Non-trivial consistency checks are performed and we compare with corresponding results in the literature. Analytic results are supplied in the supplementary materials.

  1. Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order in harmonic coordinates

    gr-qc 2026-01 conditional novelty 7.0 of 10

    The 4.5PN radiation-reaction acceleration of nonspinning compact binaries is derived in harmonic coordinates, including a dimensional-regularization pole, and is shown to satisfy flux-balance laws and Lorentz invariance.

  2. Radiation-reaction driven dynamics at the third-and-a-half post-Newtonian order in different gauges

    gr-qc 2026-08 conditional novelty 6.0 of 10

    A method is given for obtaining the 3.5PN radiation-reaction force and orbit correction in any Hamiltonian coordinate system by transforming from harmonic coordinates.
