Fig. 8

Same as in Fig. 7, but now for a different initial rotation period of 9 h. In many respects, the evolution is similar to that shown in the previous figure with one important exception: at ≃ 2.25 Gyr (vertical dashed line 1) the spin state becomes captured in the Slivan state of the s6 precession frequency; it remains located in the Slivan state until ≃5 Gyr (verticaldashed line 2), when the amplitude of resonant libration grows to 180°. Consequently, the spin state leaves the Slivan state and continues to evolve primarily by YORP torques: the obliquity drifts to small values and the rotation period slowly increases; at ≃ 5.85 Gyr (highlighted by the arrows), both roughly match the current values of (208) Lacrimosa. As the rotation period continues to grow, the spin evolution follows the trend seen also in Fig. 7: it starts to closely follow the Cassini state 2 associated with the s precession frequency (eventually becoming captured in the corresponding Slivan state).
