Figure 8: Dynamical maps of the inner region of the asteroidal belt on the (a,e)-plane ( left) and (a, I)-plane ( right) of the osculating elements (the initial inclination on the left panel and initial eccentricity on the right panel were fixed at the current values of those of Vesta). The domains of chaotic motion (the vertical dark strips) are associated with two- and three-body mean-motion resonances and are labeled on the top of the panels by numbers from 1 to 9 (see Table 3). For reference we also show the location in the proper elements space of Vesta family members, in cyan, Massalia, in blue, Nysa, in yellow, Erigone, in magenta, and Baptistina, in green. |
