Precision observations of orbital systems have recently emerged as a
promising new means of detecting gravitational waves and ultra-light dark
matter, offering sensitivity in new regimes with significant discovery
potential. These searches rely critically on precise modeling of the dynamical
effects of these signals on the observed system; Tuttavia, previous analyses
have mainly only relied on the secularly-averaged part of the response. Noi
introduce here a fundamentally different approach that allows for a fully
time-resolved description of the effects of oscillatory metric perturbations on
orbital dynamics. We find that gravitational waves and ultra-light dark matter
can induce large oscillations in the orbital parameters of realistic binaries,
enhancing the sensitivity to such signals by orders of magnitude compared to
previous estimates.
