TL;DR: The 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metres-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal, is introduced.

TL;DR: The 4-metre Multi-Object Spectroscopic Telescope (4MOST) as mentioned in this paper is a high-multiplex, wide-field spectroscopic survey facility under development for the VISTA at Paranal.

TL;DR: In this paper, the authors compare the performance of this pipeline by comparing the derived stellar parameters and abundances to those inferred from optical spectra and analysis for several hundred stars, and show that magnesium is the most accurate alpha-element derived by ASPCAP, and shows a very clear thin/thick disk separation.

TL;DR: In this article, the authors analyzed high-resolution and high-signal-to-noise-ratio HARPS spectra of a sample of solar-like stars to obtain precise determinations of their atmospheric parameters and abundances for 25 elements and ions belonging to the main nucleosynthesis channels.

TL;DR: In this article, the authors investigated the dependence on metallicity on stellar ages and abundance ratios for a sample of solar-like stars and applied their relations to Gaia-ESO samples of open clusters and field stars.
