The cluster Terzan 5 as a remnant of a primordial building block of the Galactic bulge
TLDR
It is reported that Terzan 5, a globular-cluster-like system in the Galactic bulge, has two stellar populations with different iron contents and ages, which could be the surviving remnant of one of the primordial building blocks that are thought to merge and form galaxy bulges.
Gaia FGK benchmark stars: Metallicity
Context. To calibrate automatic pipelines that determine atmospheric parameters of stars, one needs a sample of stars, or “benchmark stars”, with well-defined parameters to be used as a reference.
THE CHEMICAL COMPOSITION OF RED GIANT STARS IN FOUR INTERMEDIATE-AGE CLUSTERS OF THE LARGE MAGELLANIC CLOUD*
This paper presents the chemical abundance analysis of a sample of 27 red giant stars located in four populous intermediate-age globular clusters in the Large Magellanic Cloud, namely NGC 1651, 1783,
News from the Galactic suburbia: the chemical composition of the remote globular cluster NGC 2419 ⋆
We present the chemical analysis of 49 giant stars of the globular cluster NGC 2419, using medium resolution spectra collected with the multi-object spectrograph DEIMOS@Keck. Previous analysis of
New Density Profile and Structural Parameters of the Complex Stellar System Terzan 5
Terzan 5 is a globular cluster-like stellar system in the Galactic bulge which has been recently found to harbor two stellar populations with different iron content and probably different ages. This
The Gaia-ESO Public Spectroscopic Survey
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 ...
The horizontal branch in the UV colour–magnitude diagrams – II. The case of M3, M13 and M79
We present a detailed comparison between far-ultraviolet (UV)/optical colour–magnitude diagrams obtained with high-resolution Hubble Space Telescope data and suitable theoretical models for three
The Globular Cluster NGC 1978 in the Large Magellanic Cloud
We have used deep, high-resolution Hubble Space Telescope ACS observations to image the cluster NGC 1978 in the Large Magellanic Cloud. This high-quality photometric data set allowed us to confirm
The Gaia-ESO Survey: the analysis of high-resolution UVES spectra of FGK-type stars
Context. The ongoing Gaia-ESO Public Spectroscopic Survey is using FLAMES at the VLT to obtain high-quality medium-resolution Giraffe spectra for about 10(5) stars and high-resolution UVES spectra
Looking Outside the Galaxy: The Discovery of Chemical Anomalies in Three Old Large Magellanic Cloud Clusters
By using the multifiber spectrograph FLAMES mounted at the ESO-VLT, we have obtained high-resolution spectra for 18 giant stars, belonging to 3 old globular clusters of the Large Magellanic Cloud
