Possible evolutions for the spin of Hydra. We show the rotation (in red) and the cosine of the obliquity (in blue). We numerically integrated the equations of the three-body problem together with Eqs. (A.1), (A.2), and (A.13) for the rotational motion. We adopt an initial retrograde rotation of 4.4 days with different initial values of θ, and an initial obliquity of 30°.
