TL;DR: In this article, the authors used the Gaia-ESO survey data to derive the radial velocities, stellar atmospheric parameters, metallicity, and elemental abundances for stars targeted as potential members of the NGC 4815 open cluster.

TL;DR: In this article, a Monte-Carlo simulation was performed to estimate the effect of binary star orbits on the measured velocity dispersion in dwarf spheroidal galaxies, and it was shown that the contribution of binary stars to the velocity distribution is small, although this is dependent on the measuring errors and on the number of years over which measurements have been taken.

TL;DR: In this article, spectra of hot stars from the RAVE Survey were used to investigate the visibility and properties of five diffuse interstellar bands previously reported in the literature, and the presence of a DIB at 8648 Ang was confirmed.

TL;DR: For metal-poor benchmark stars, disagreement has been reported in this paper, where a set of 'benchmark' stars whose fundamental properties are well determined are used for validation of large stellar surveys of the Milky Way.

TL;DR: In this paper, the mass loss rates of AGB stars are derived from ISOGAL mid-infrared photometry and models of stellar spectra adjusted for the presence of optically-thin circumstellar silicate dust.
