Abstract: Intermediate mass-ratio coalescences (IMRACs) are potential signals of ground-based and space-based gravitational observatories. Much semi-analytical work is required in the upcoming years to deduce their waveforms to required accuracy for precision tests within general relativity. In this paper, we present analytic results to the Teukolsky perturbation around a high spin black hole including spin coupling and finite size effects. We find scaling behavior close to the smallest specific angular momentum, and we discuss features of spin and quadrupole couplings.
