摘要: We present here in full detail the evolution of angular momentum deficit (AMD) during collisions as it was described (Laskar, PRL,2000). Since then, AMD has been revealed to be a key parameter for understanding outcome planetary formation models. define AMD-stability criterion that can easily verified on newly discovered system. show how used establish classification multiplanet systems order exhibit are long-term stable because they AMD-stable, and those AMD-unstable which then require some additional dynamical studies conclude their stability. The is applied 131 from Extrasolar Planet Encyclopaedia database (this http URL) orbital elements sufficiently well known.
