Elliptic two-dimensional invariant tori for the planetary three-body problem / L. Biasco, L. Chierchia, E. Valdinoci. - In: ARCHIVE FOR RATIONAL MECHANICS AND ANALYSIS. - ISSN 0003-9527. - 170:2(2003), pp. 91-135.
Abstract:
The spatial planetary three-body problem (i.e., one ‘‘star’’ and two ‘‘planets’’, modelled by three massive points, interacting through gravity in a three dimensional space) is considered. It is proved that, near the limiting stable solutions given by the two planets revolving around the star on Keplerian ellipses with small eccentricity and small non-zero mutual inclination, the system affords two-dimensional, elliptic, quasi-periodic solutions, provided the masses of the planets are small enough compared to the mass of the star and provided the osculating Keplerian major semi-axes belong to a two-dimensional set of density close to one.
