We study the chemical composition of 5 giant stars in the globular cluster Terzan 7 associated with the Sagittariusdwarf spheroidal galaxy (Sgr dSph), based on high resolution UVES-VLT spectra. We confirm the metallicity found by previoushigh resolution investigations: [Fe/H]∼ −0.6. We also show that this cluster displays the same low α−element… Expand

Whiting 1: the youngest globular cluster associated with the Sagittarius dwarf spheroidal galaxy ,,
Context. Recently, Carraro (2005) drew attention to the remarkable star cluster Whiting 1 by showing that it lies about 40 kpc from the Sun and is therefore unquestionably a member of the GalacticExpand
Globular clusters in the Sagittarius stream
We reconsider the case for the association of Galactic globular clusters (GCs) to the tidal stream of the Sagittarius dwarf spheroidal galaxy (Sgr dSph), using Gaia DR2 data. We use RR Lyrae to traceExpand
Detailed Chemical Abundances of Four Stars in the Unusual Globular Cluster, Palomar 1
Detailed chemical abundances for twenty one elements are presented for four red giants in the anomalous outer halo globular cluster Palomar 1 (RGC = 17.2 kpc, Z = 3.6 kpc) using high-resolution (R =Expand
Sulfur in the globular clusters 47 Tucanae and NGC 6752
Context. The light elements Li, O, Na, Al, and Mg are known to show star-to-star variations in the globular clusters 47 Tuc and NGC 6752. Such variations are interpreted as coming from processing inExpand
Chemical abundances of giant stars in NGC 5053 and NGC 5634, two globular clusters associated with the Sagittarius dwarf Spheroidal galaxy?
The tidal disruption of the Sagittarius dwarf Spheroidal galaxy (Sgr dSph) is producing the most prominent substructure in the Milky Way (MW) halo, the Sagittarius Stream. Aside from field stars, theExpand
The Gaia-ESO Survey: Detailed abundances in the metal-poor globular cluster NGC 4372
We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey. This is the firstExpand
Evidence for a chemical enrichment coupling of globular clusters and field stars in the Fornax dSph
The globular cluster H4, located in the center of the Fornax dwarf spheroidal galaxy, is crucial for understanding the formation and chemical evolution of star clusters in low-mass galacticExpand
Na-O anticorrelation and HB. III. The abundances of NGC 6441 from FLAMES-UVES spectra
Aims. The aim of the present work is to determine accurate metallicities for a group of red giant branch stars in the field of the bulge Globular Cluster NGC 6441. This is the third paper in a seriesExpand
ARP 2 and Terzan 8: a Detailed Chemical Analysis
To compare the globular clusters (GCs) associated with the Sagittarius Galaxy (Sgr) we report the results obtained from new high-resolution spectra of red giant stars in Terzan 8 and Arp 2, collectedExpand
From globular clusters to the disc: the dual life of our Galaxy
The halo and disc globular cluster population can be used as a tracer of the primordial epochs of the Milky Way formation. In this work, literature data of globular clusters ages, chemicalExpand
