TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.

TL;DR: In this paper, the authors present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular clusters (GCs), derived from the homogeneous analysis of high-resolution FLAMES/GIRAFFE spectra.
Journal ArticleDOI
A Helium Spread among the Main-Sequence Stars in NGC 2808
TL;DR: In this article, the color distribution of the main sequence of the globular cluster (GC) NGC 2808 was studied based on deep HST WFPC2 photometry of a field in the uncrowded outskirts of the cluster.
Journal ArticleDOI

TL;DR: In this article, the abundances of light elements, α-elements, and Fe-group elements from high-resolution FLAMES spectra are presented for 76 red giant stars in NGC 6715 (M 54), a massive globular cluster (GC) lying in the nucleus of the Sagittarius dwarf galaxy.
Journal ArticleDOI
