TL;DR: In this paper, a high-resolution spectroscopic study of 714 F and G dwarfs and subgiant stars in the Solar neighbourhood was conducted, where the star sample has been kinematically selected to trace the Galactic thin and thick disks to their extremes, the metal-rich stellar halo, sub-structures in velocity space such as the Hercules stream and the Arcturus moving group, as well as stars that cannot be associated with either the thin disk or the thick disk.

TL;DR: In this paper, the Geneva-Copenhagen survey was used to estimate stellar effective temperatures and metallicity scales for a Bayesian analysis of stellar ages, which is used for a better match to theoretical isochrones, which can provide better constraints on the physical processes relevant in the build-up of the Milky Way disc.

TL;DR: In this paper, the authors presented elemental abundance trends in the Galactic thin and thick disks in the metallicity regime -0.8 < [Fe/H < +0.4] and showed that the currently most likely formation scenario is a violent merger event or a close encounter with a companion galaxy.

TL;DR: In this article, the Geneva-Copenhagen survey was used for a re-analysis of the spectral properties of the stars in the solar neighborhood and the results showed that the stars are on average 100 K hotter and 0.1 dex more metal rich, which shifted the peak of the metallicity distribution function around the solar value.

TL;DR: The Gaia-ESO Public Spectroscopic Survey has begun and will obtain high quality spectroscopy of some 100000 Milky Way stars, in the field and in open clusters, down to magnitude 19, systematically.
