Description

We calculate the evolution and gravitational-wave emission of a spinning compact object inspiraling into a substantially more massive (non-rotating) black hole. We extend our previous model for a non-spinning binary [Phys. Rev. D 93, 064024] to include the Mathisson-Papapetrou-Dixon spin-curvature force. Using a generalized osculating element prescription we compute inspirals where the spin and orbital angular momentum are not parallel and the orbital plane precesses. For spin-aligned binaries we calculate the dephasing of the inspiral and associated waveforms with respect to models that do not include spin-curvature effects.
