July 24, 2018 We have created a new interactive plot that gives a new way of looking at the population of exoplanets that we know of in the nearby solar neighbourhood. On this plot the Sun is at the centre and the various planets can be seen at their respective distances from our Sun. This gives quite an interesting perspective.

July 7, 2018 There is a new section dedicated to planets in stellar binary systems. A plot is computed from the database to show the planets' locations compared to the stellar companions and the theoretical stability limit to form planets around binaries for all systems with binaries at <200au.

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.
