Investigating Inspiral Gravitational Waveform Models with Eccentricity and Precession

Waveform models are crucial for gravitational wave data analysis, and having models that include both the effects of eccentricity and precession is important for increasing the physics output with parameter estimation, especially as recent work suggests the effects on the waveform could mimic each other. In this talk, we investigate the post-Newtonian inspiral dynamics of compact binary coalescence that include both the effects of eccentricity and spin-induced precession. We use these dynamics to generate waveform polarizations, and make comparisons to other waveform models which include either eccentricity or precession, to assess the accuracy and systematics of our approach.
