Same as Fig. 10 but only for three bodies (A, B, C), where A represents Aa+Ab. Without a protection mechanism, the Kozai oscillations were triggered, with a period of ≃11500 y. The angular momenta L_B and L_C still describe conical surfaces, but now their mutual angle J exhibits large oscillations, which triggers correlated oscillation of eccentricities and inclinations of the inner and outer orbits.
