Abstract

We present in detail an Effective Field Theory (EFT) formulation for the essential case of spinning objects as the components of inspiralling compact binaries. We review its implementation, carried out in a series of works in recent years, which leveled the high post-Newtonian (PN) accuracy in the spinning sector to that, recently attained in the non-spinning sector. We note a public package, "EFTofPNG", that we recently created for high precision computation in the EFT of PN Gravity, which covers all sectors, and includes an observables pipeline.
