Projects of the Exoplanets team

Keywords Exoplanets in the habitable zone, detection and caracterisation, F-G-K-M stars, stellar variability, host star characterisation
Motivations Our team has a long history in discovering and studying planets around very-low-mass stars, in particular with both Doppler spectroscopy and transit photometry methods. Over the years our surveys have become sensitive to ever lower-mass, smaller planets and did detect several exo-Earths in the so called “habitable zones” of their host stars. (…)

Keywords Orbital characterisation, debris discs, planet-disc interaction, exozodiacal cloud, dust
Motivations
The ingredients of extra-solar systems are diverse and not limited to the telluric, gaseous and icy planets, observed in our solar system in the same orbital plane at increasing distances from the Sun. We also observe belts of planetesimals or interplanetary dust, at various distance from the central star, as well as planets whose position or orbit inclination are signposts for (…)
