Atmosphere: the new science frontier
The last twenty years have witnessed an exceptionally fast development in the field of the extra solar planets. The known exoplanets, almost 4000 to date, already show how diverse the planets in our galaxy can be. Exoplanets A focuses on the characterization of their atmosphere, a new field of research, including spectroscopic observations of an exoplanet atmosphere. At stake are the molecular composition of giant exoplanet atmospheres, tracing their formation and evolution, as well as the atmosphere of rocky exoplanets and the presence of biosignature gases. However, the observations are challenging because the signal is often embedded in instrumental and telescope systematic noise.
The Science sections of the Knowledge server will provide access to scientific resources delivered by the Exoplanets A. These resources are available using the lateral menu with four main sub-sections.
“Space mission“ provides the ESA and NASA space observatories that have produced the dataset required to perform data reduction. The project will also ready us to rapidly exploit data from future space facilities such as the James Webb Space Telescope and the ARIEL mission.
“Codes“ gives access the novel data calibration and spectral extraction tools, as well as novel retrieval and simulation tools, based on 3D models of exoplanet atmospheres, to exploit space mission archival data from HST, Spitzer and Kepler archives and produce a homogeneous and reliable characterization of exoplanet atmospheres….
“Catalogues“ opens to source tables and dataviz on three main topics : exoplanets, host stars and stars-planets interaction. We collect a coherent and uniform database of the relevant properties of host stars from ESA science archives (XMM, Gaia), combined with other space mission and ground-based data. These source catalogues will be accompanied/interpreted with models to assess the importance of stars-planets interactions.
“Publications“ summarizes the knowledge gained from this project including peer- review publications and direct access to the most significant science results on exoplanet atmosphere.
