Abstract

Within the framework of 2PN black-hole binary spin precession, we explore configurations where one of the two spins oscillates from being completely aligned with the orbital angular momentum to being completely anti-aligned with it during a single precession cycle. This wide nutation is the extreme limit of the generic phenomenon of spin nutation in black-hole binaries. Crucially, wide nutation happens on the short precession time scale and it is not a secular effect due to gravitational-wave radiation reaction. The spins of these binaries, therefore, flip repeatedly as one of these special configurations is entered. Binaries with total mass M, mass ratio q, and dimensionless spin Χ_1 (χ_2) of the more (less) massive black hole are allowed to undergo wide nutation at binary separations r ⩽ r_(wide) ≡ [(qχ_2−χ_1)/(1−q)]^2M. Sources that are more likely to nutate widely have similar masses and effective spins close to zero.
