Variation of the Equator due to a Highly Inclined and Eccentric Disturber

Figure 3

(a), (c): the lighter points were obtained taking into account the and equations in the integration, while in the thick points these contributions were neglected. (b), (d): time variation of the eccentricity (b) and inclination (d) for two orbits. Initially their paths are similar, but when their semimajor axes enter the resonance region, a jump appears in the eccentricity (b), first in the orbit which contains the effect of the precession. The same occurs for the inclination (d), that is, the precession accelerates the onset of the jump of the inclination.
