The AMBRE project: Results from the MATISSE analysis of the ESO-FEROS archived spectra

摘要

The goal of AMBRE, a joint project between ESO and the Observatoire de la Cote d’Azur, is to provide a homogeneous determination of the stellar parameters (including mean metallicity and some chemical abundances) for the archived spectra of the FEROS, HARPS, UVES and Flames/GIRAFFE spectrographs. We present here a preliminary analysis of the FEROS stellar sample. The stellar parameters, derived using the stellar classification algorithm MATISSE, have been combined with distances and radial velocities in order to explore current theories regarding galactic stellar populations. We have reviewed the sample for potential disk stars with which we can explore kinematic and chemical signatures of the thin and thick disk. We present here a comparison of the potential disk stellar sample to the analysis of 66 disk stars that was carried out in.
