Inspiraling compact objects with generic deformations

Abstract
Gravitating bodies are typically deformable and deviate from spherical symmetry and even axisymmetry. These deviations are encoded in the body's so-called mass and current multipole moments. This paper studies leading corrections to binary dynamics when the compact objects involved have arbitrary mass quadrupole moments. These corrections are important in modeling waveforms and interpreting gravitational wave data.
