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

Three Jupiter-mass planets are detected around two low-luminosity red giants with 15–18 yr CORALIE RVs; a multi-exposure strategy averages pulsations below 5 m/s.
Resolves six speculative companions into one giant planet, one eccentric brown dwarf, two low-mass stars, and two stars with no detectable companions.
