Stellar parameters for stars of the CoRoT exoplanet field

摘要: Context. Spectroscopic observations represent a fundamental step in the physical characterization of stars and, particular, precise location HR diagram. Rotation is also key parameter, impacting stellar properties and evolution, which modulates interior manifests itself on surface stars. To date, lack analysis based large samples has prevented our understanding real impact parameters rotation evolution as well behavior abundances. The space missions, CoRoT Kepler, are providing us with periods for thousands stars, thus enabling robust assessment different populations evolutionary stages. For these reasons, followup programs to increasing returns missions. An that combines spectroscopic data rotation/modulation obtained from missions provides basis establishing angular momentum solar-like at stages, relation other relevant chemical parameters. Aims. support computation interpretation associated rotational modulation, oscillations, variability located fields, we conducting survey fields already observed by satellite. These allow compute sample. Methods. Using UVES/VLT Hydra/Blanco, standard techniques, computed (Teff ,l og (g), [Fe/H], vmic, vrad, v sin (i), A(Li)) sample targets. Results. We provide comprised 138 Our shows ranging main sequence red giant branch, range spectral type F K. agreement typical values reported FGK However, report three presenting abnormal lithium fields. properly characterize intrinsic results reveal important differences distributions metallicity,Teff, status belonging independently ground-based photometric surveys. Conclusions. catalog, much-needed information targets, will be importance successful accomplishment several related mission, it help further boost scientific return this mission.
