Development of analysis tools to analyze the oscillations of planet-host stars, in preparation for the PLATO mission
PLATO (PLAnetary Transits and Oscillation of stars) is an ESA space mission that will detect terrestrial exoplanets at orbits up to the habitable zone of solar-type stars and characterize their bulk properties. PLATO will provide key information (planetary radii, mean densities, ages, stellar irradiation, and architecture of planetary systems) needed to determine the habitability of these unexpectedly diverse new worlds. PLATO will characterize hundreds of rocky (including Earth twins), icy or giant planets, as well as the architecture of their planetary system, to fundamentally enhance our understanding of the formation and the evolution of planetary systems.
These goals will be achieved through:
- planet detection and radius determination from photometric transits,
- determination of planet masses from ground-based radial velocity follow-up,
- determination of accurate stellar masses, radii, and ages from asteroseismology, and
- identification of bright targets for atmospheric spectroscopy.
Within this general scientific framework, various PhD projects in preparation for the mission are available.
