摘要: The angular momentum deficit (AMD)-stability criterion allows to discriminate between a priori stable planetary systems and for which the stability is not granted needs further investigations. AMD-stability based on conservation of AMD in averaged system at all orders averaging. While rigorous, only absence mean-motion resonances (MMR). Here we extend take into account resonances, more specifically overlap first-order MMR. If MMR islands overlap, will experience generalized chaos leading instability. Hamiltonian two massive planets coplanar quasi-circular orbits can be reduced an integrable one degree freedom problem period ratios close We use derive new This unifies previous criteria proposed literature admits obtained initially circular eccentric as limit cases. then improve definition short term generated by overlap. analyze outcome this improved selected multi-planet from Extrasolar Planets Encyclopaedia.
