The ExoAtmospheres Database imports the stellar and planetary parameters from the Exoplanet Encyclopaedia database, and when some parameters are missing, it imports them from the NASA Exoplanet Archive. The main purpose of the database is to provide updated and easy to navigate information on exoplanet atmospheric detections.
Find information on a given planet
By clicking on the planet name in the main table, a new page will open will all entries referencing that planet. The full history of entries is documented with direct links to the relevant publication. Entries in the database can report new detections, upper limits, or may report conflicting results (i.e. a non-detection of previously reported features or re-analysis of a given dataset). ExoAtmospheres makes no attempt to arbitrate/reconcile conflicting reports. They are all listed in the planet page and both detections and non-detections are listed and referenced.
ExoAtmospheres is meant to be an easy tool to quickly find out how many planets of a given type have had their atmospheres characterized, and what time of atmospheric features one can derive from them. Explore the database filtering by molecules, planetary temperature, planetary radius or host star magnitude. It is also a great tool to easily explore the bibliography on your specific research subject.
Molecules/atoms in green color reported a detection. Orange ones report hints of detection (at a non-statistically significant level) or upper limits derived from the data. Red ones report non-detections, and should be associated to previous claims.
You can add an entry to the database by simply having handy bibcode or arXiv ID number of your publication. In a single entry you can add only one paper reference. And this paper can be associated to one or several atomic species (just keep hitting "Add Molecule" button) , the detection of the planetary albedo and the albedo value ( "Add Albedo" button) , the detection of a phase curve ( "Add phase curve" button), or any combination of the former.
When you submit an entry, the data is not immediately visible in the database. It has to go through a human-vetting control to make sure the entry reflects a proper publications and claims are justified. So please be patient.
Be proactive: We rely on you inputs wen publishing a new paper to maintain the database up to date which in return will give visibility to your work. Please help us maintain it as complete as possible by submitting your own (or anyone else's) results via the submission form.
For easy exploration and filtering, we have subdivided the planets in several planetary types, according to their radius and Equilibrium temperature.
| Planet temperature | Planet radius | ||||
|---|---|---|---|---|---|
| UltraHot | >2000 K | Jupiter | >8 Re | >0.71 Rj | |
| Hot | 2000-800 K | Neptune | 3-8 Re | 0.27-0.71 Rj | |
| Warm | 800-400 K | Sub-Neptune | 2-3 Re | 0.18-0.27 Rj | |
| Temperate | 400-250 K | Super-Earth | 1.2-2 Re | 0.11-0.18 Rj | |
| Cold | <250 K | Earth-size | >8 Re | 0.06-0.11 Rj | |
| Sub-earths | <0.7 Re | <0.06 Rj |
When Equilibrium Temperature is not available from the Exoplanet Encyclopaedia database, we calculate ti following this formulation, assuming a bond albedo of 0.2 (R < 2 Re) and 0.1 for (R > 2 Re)
