Orbital motion of spinning compact binaries — •Manuel Tessmer, Johannes Hartung, and Gerhard Schäfer — TPI, Physikalisch-Astronomische Fakultät, Friedrich-Schiller-Universität Jena

A Keplerian-type parameterization for the solutions to post-Newtonian accurate equations of motion for spinning compact binaries is obtained including both spin-orbit and spin-spin interactions. For arbitrary mass ratios the spin orientations are taken to be parallel or antiparallel to the orbital angular momentum vector, for nearly equal masses no assumptions about the spin orientations are made but quasi circularity of the orbits is chosen.
