SUMMARY:

Recent detections of gravitational waves, together with the increasing precision of electromagnetic observations of neutron
stars and black holes, have expanded the possibility of testing the theory of General Relativity. In this work, we parameterize
extensions of General Relativity (GR), adding terms of high curvature, built from the fourth powers of the Riemann tensor,
therefore, departing from GR in the ultraviolet (UV). The presence of these operators modifies the gravitational potential
between compact objects, as well as their multipole moments. Through an Effective Field Theory approach, we calculate the
corrections to the gravitational potential and radiative multipole within the post-Newtonian approximation to GR and obtain
also the equations of motion for the spin and these quantities are directly comparable with astronomical observations.
