abstract
The paper generalizes the structure of gravitational waves from orbiting spinning binaries under leading order spin-orbit coupling, as given in the work by K\"onigsd\"orffer and Gopakumar [PRD 71, 024039 (2005)] for single-spin and equal-mass binaries, to unequal-mass binaries and arbitrary spin configurations. The orbital motion is taken to be quasi-circular and the fractional mass difference is assumed to be small against one. The emitted gravitational waveforms are given in analytic form.

Analytic Keplerian-type parametrization for general spinning compact binaries with the leading order spin-orbit interaction
A fully analytic Keplerian-type parametrization is derived for conservative motion of a spinning binary with arbitrary masses, eccentricity, and spin orientations, at leading spin-orbit order.
