ExoAtmospheres
IAC community database for exoplanet atmospheric observations

 

This Exoplanet Atmospheres Database is built for the community and maintained by the community. This is an exciting and vibrant field of research, where new discoveries and publications occur at a very fast pace and it is easy to miss many interesting results. The main purpose of this database is to become a quick and useful repository of all available exoplanet atmospheres observations, and also to help in the gathering of useful references for a given planet or plane types.

Please help us maintain it as complete as possible by submitting your own (or anyone else's) results via the submission form above. We are a small team and we will maintain and improve this site on a best effort basis. We will be happy for any feedback you might have for us (Contact: exoatm@iac.es).


Use the Search... boxes to filter data by column value. For numeric values you can use comparison symbols like >, <, >=, <= and logic operators.
