We explore spinning, precessing, unequal mass binary black holes to display the long-term orbital angular momentum,, flip dynamics. We study two prototypical cases of binaries with mass ratiosandand a misaligned spin of the large black hole (with an intrinsic spin magnitude of). We conduct full numerical simulations, for nearly 14 and 18 orbits, respectively, to evolve the binary down to a merger and display a full-flip cycle. The pattern of radiation of such systems is particularly interesting, displaying strong polarization-dependent variation of amplitudes at precessional frequencies, leading to distinctive observational consequences for gravitational wave detectors. These waveform features are strongly directional dependent, and measurements of gravitational wave polarizations can be exploited to disentangle the binary’s parameters in various astrophysical scenarios.
