Full-analytic frequency-domain gravitational wave forms from eccentric compact binaries to first post-Newtonian order — •Manuel Tessmer and Gerhard Schäfer — Friedrich-Schiller-Universiät Jena

We provide full-analytical gravitational wave forms for eccentric non-spinning compact binaries of arbitrary mass ratio in the time Fourier domain to first post-Newtonian order in both conservative orbital motion and gravitational wave amplitudes. These amplitudes are given in spherical tensor components. The leading order radiation reaction effects are included to depict the inspiral with the help of the stationary phase approximation. To extend the presented computation to second post-Newtonian order, we present a full-analytical inversion formula of the Kepler equation in harmonic coordinates.
