June 7, 2017 The Angular Momentum Deficit (AMD) is a key parameter to understand the long-term stability of planetary systems. Indeed the AMD can be used to define a criterion guaranteeing the long-term stability: the AMD-stability. The 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. A tool for computation of AMD-stability is accessible in the planet page of the following sytems : 24 Sex - 47 Uma - 55 Cnc - 61 Vir - BD-06 1339 - BD-08 2823 - CoRoT-7 - GJ 163 - GJ 180 - GJ 3293 - GJ 649 - GJ 667 C - GJ 676 A - GJ 682 - GJ 785 - GJ 832 - GJ 876 - HAT-P-13 - HD 10180 - HD 102272 - HD 108874 - HD 109271 - HD 110014 - HD 113538 - HD 11506 - HD 117618 - HD 11964 - HD 125612 - HD 12661 - HD 128311 - HD 133131 A - HD 134060 - HD 134606 - HD 134987 - HD 136352 - HD 13808 - HD 13908 - HD 141399 - HD 142 - HD 143761 - HD 1461 - HD 147018 - HD 147873 - HD 154857 - HD 155358 - HD 159243 - HD 159868 - HD 1605 - HD 163607 - HD 164922 - HD 168443 - HD 169830 - HD 177830 - HD 181433 - HD 183263 - HD 187123 - HD 190360 - HD 20003 - HD 200964 - HD 202206 - HD 204313 - HD 20781 - HD 207832 - HD 20794 - HD 215152 - HD 215497 - HD 21693 - HD 217107 - HD 219828 - HD 31527 - HD 33844 - HD 3651 - HD 37124 - HD 37605 - HD 38529 - HD 39194 - HD 40307 - HD 45364 - HD 47186 - HD 4732 - HD 47366 - HD 51608 - HD 52265 - HD 5319 - HD 60532 - HD 65216 - HD 67087 - HD 69830 - HD 73526 - HD 74156 - HD 7449 - HD 75784 - HD 7924 - HD 85390 - HD 87646A - HD 89744 - HD 92788 - HD 93385 - HD 9446 - HD 96700 - HIP 14810 - HIP 5158 - HIP 57274 - HIP 65407 - HIP 67851 - K2-3 - KELT-6 - Kapteyn's - Kepler-10 - Kepler-11 - Kepler-23 - Kepler-289 - Kepler-419 - Kepler-454 - Kepler-46 - Kepler-51 - Kepler-56 - Kepler-68 - Kepler-79 - Kepler-87 - NN Ser (AB) - Pr 0211 - Trappist-1 - TYC+1422-614-1 - WASP-41 - Wolf 1061 - XO-2S - eta Cet - mu Ara - nu Oph - ups And – reference : Laskar J. & A.
