Our Planets in Binaries database has been upgraded and now hosts a specific database on circumbinary planets (P-type orbits), accessible from the main database page or directly here. As for the database on S-type orbits, it contains both overview graphs and machine-readable tables with the systems' main characteristics.

We are pleased to announce the first release of an extended version of the Encyclopaedia of extrasolar planets, which becomes the Encyclopaedia of exoplanetary systems. Some of these pages are still in beta version. We are actively working on new updates to the current website. Please do not hesitate to contact us at vo.exoplanet@obspm.fr if you have any questions or comments.

The first bunch of planet candidates are delivered by GAIA DR3 (click on status: candidates at the upper left of the catalog to see them): 63 are astrometric detections and 9 are from radial velocities. GAIA will provide thousands of them in the near future. Thanks to F.Arenou, N. Leclerc, A. Sozzetti (Gaia DPAC), C.Chauvin, F.Roques, Q. Kral & J. Schneider (exoplanet.eu Team)

Our planets in binaries sub-page lists 154 confirmed planets on an S-type orbit (orbiting one of the two stellar components) in <500au separated binaries.

Today, the catalog shows 5014 confirmed planets, 2638 candidates and 821 multiple planets sytems.

Our page listing exoplanets in binary systems went through a major update, now providing the inclusion of a downloadable machine-readable table with the main characteristics of all known (S-type) planet-hosting binaries of separation <500au (see here).

We have just gone through a major update adding hundreds of new planets to our database!

A new tool is now accessible on the exoplanet.eu database. This tool can be used to easily simulate the climate on terrestrial planets. It is accessible here.

All of our database is accessible in python via our API. We have added a tutorial to use the API to query our database and collect/handle the data you want in an easy way.

Today is a celebration day as we are now over 4000 planets validated in our database and this number will grow very quickly thanks to intensive on-going work!

Warning : Announcements of K2 planets can be duplicated. -The planet of the star EPIC 201498078 has been announced as K2-261 b by Johnson et al., MNRAS, august 2018 and as K2-161 b by Brahms et al. , MNRAS, november 2018. - Mayo et al. 2018 gives also the name K2-161 b to EPIC 201231064 b. - The two planets of the star 2MASS J08452605+1941544 are simultaneously announced by Rizzuto et al. (2018 ) as K2-264 b and c and by Livingston et al. (2018) as EPIC 211964830 b and c.

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.

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.

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.
