Re-recognized universality of Kozai oscillation on three-body dynamics

Proceedings of the Japan Academy. Series B, Physical and Biological Sciences
In 1962, Yoshihide Kozai reported his findings on the secular dynamics of asteroids moving in orbits with high inclination and eccentricity. In contrast to the classic understanding of the stability of planetary motion in the solar system, Kozai showed ...
