The “Planetary Systems” team at IA focuses its activities around the two major branches, namely Exoplanet research and Solar System atmospheres.

This research focuses on multiple complementary aspects:

1. the search and characterization of exoplanets using state-of-the-art radial velocity and transit photometry data;
2. the understanding of astrophysical sources of noise for the detection and characterization of planets as well as methods to correct/model them;
3. the study of planet-host stars as a way to characterize planets as well as their properties and formation processes;
4. the detection and characterization of exoplanet atmospheres using broad-band photometry and high-resolution spectroscopy;
5. the study of solar-system planet atmospheres, with clear synergies with the exoplanet side;
   
6. the study of minor bodies in the solar system and the cratering history in rocky planets.

All this research is supported by our strong leading participation in a number of international projects and collaborations, including ESO and ESA projects and missions:

• ESO’s ESPRESSO@VLT
• The ESA CHEOPS mission
• SPIROU@CFHT
• ESO’s NIRPS near-IR spectrograph
• ESA’s PLATO mission
• ESA’s ARIEL mission
• ESO’s HIRES@ELT spectrograph
