Resonances around Chariklo. Upper panel: trajectories (shown by light gray lines) around the corotation points, C₂ and C₄, of Chariklo, using Eq. (F.3). The dark gray ellipse is a pole-on view of Chariklo’s shape, taken from Table 2. The two green circles mark the radii of C1R and C2R rings. Red circle: First-order 2/3 resonance caused by Chariklo’s triaxial shape. Solid black circle: first-order 1/2 resonances caused by a mass anomaly. Dashed black circle: second-order 1/3 and 3/5 resonances caused by a mass anomaly. More resonances radii are plotted in the lower panels. Middle panel: maximum eccentricity, e_max (in log-scale), reached by a particle initially on a circular orbit, reproducing the behavior displayed in Fig. 3 for each SOR. Red curves: SORs caused by the triaxial shape of Chariklo. Black curves: SORs caused by a mass anomaly, µ = 10⁻³. The orange box indicates Chariklo’s largest semi-axis, while the gray box shows the radial extension of the corotation zone, i.e., the full width of the corotation resonance (Eq. (F.4)). Lower panel: same, but for second-order resonances. The radii of the rings C1R and C2R are marked in green. The purple zone is the uncertainty on the 1/3 SOR location, due to the uncertainty on Chariklo’s mass. The uncertainties on the ring radii are negligible at this scale (see Table 2).
