Abstract

The goal of AMBRE, a joint project between ESO and the Observatoire de la Cˆote 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. These parameters will be made available to the astronomical community via the ESO Archive. This will be a comprehensive spectral library with which the archived spectra can be newly explored and it will also provide a large set of homogeneously analysed reference stars with which to make comparison to other spectroscopic studies.

The stellar parameters determined in the now completed analysis of the FEROS archived spectra are presented here. The analyses of the HARPS and UVES archived spectra are underway. The FEROS stellar parameters make up the first layer of the ESO Archive spectral library which can be considered as a galactic chemical chart in its own right. We present the range of parameters that have been determined and the potential for scientific research with these parameters.
