Massive spectroscopic analysis of the stellar populations in three of the CoRoT/Exoplanet fields
Abstract
We derived the atmospheric parameters (teff, logg, met, alf), řad, and šini for 1227 CoRoT/Exoplanet targets in three of the fields observed by CoRoT. We derived the corresponding absolute magnitude using evolutionary models. We combined 2MASS colours with a new implementation of the infrared flux method, and the teff from matisse to constrain the interstellar extinction. These steps allowed us to measure the stellar distances, hence deriving kinematics information. This opened the path to the study of the stellar populations found in these \corot fields.These studies showed the potential of combining a multi-fiber instrument like FLAMES/GIRAFFE, with an automatic tool to determine efficiently atmospheric stellar parameters, as MATISSE.
