Eccentricities e of particles vs. semimajor axis a. Unlike in Fig. 7, here we do not use the quantity ā because its definition depends on the particular resonance considered (Eq. (2)). However, because e remains small, this choice does not change the interpretation of this figure taken from the run shown in Fig. 15. We note that at time T = 21 600, the narrow second-order 3/5 SOR is able to significantly perturb the ring, in spite of the fact that the first-order 2/3 SOR is still expected to exert a nonnegligible perturbation, amounting to 10% of the eccentricity forced by the 3/5 SOR. At time T = 112 000, we see the damping effect of collisions as the ring evolves between the 3/5 and 1/2 SORs. The run is stopped at T=249 720 Chariklo’s rotations, corresponding to about 200 years. We note that third-order resonances, for example the 4/7 SOR at a=1.45, have no effect on the migration. Two movies generated from snapshots stored every 360 Chariklo rotations (about 105 days) are available online:
