Abstract: (APS)
We calculate the evolution and gravitational-wave emission of a spinning compact object inspiraling into a substantially more massive (nonrotating) black hole. We extend our previous model for a nonspinning binary [Phys. Rev. D 93, 064024 (2016)PRVDAQ2470-001010.1103/PhysRevD.93.064024] to include the Mathisson-Papapetrou-Dixon spin-curvature force. For spin-aligned binaries we calculate the dephasing of the inspiral and associated waveforms relative to models that do not include spin-curvature effects. We find this dephasing can be either positive or negative depending on the initial separation of the binary. For binaries in which the spin and orbital angular momentum are not parallel, the orbital plane precesses and we use a more general osculating element prescription to compute inspirals.
