A view of the H-band light-element chemical patterns in Globular Clusters under the AGB self-enrichment scenario
F. Dell'Agli, D. A. García-Hernández, P. Ventura +7
We discuss the self-enrichment scenario by AGB stars for the formation of multiple populations in globular clusters (GCs) by analyzing data set of giant stars observed in 9 Galacti…
Chemical characterization of the globular cluster NGC 5634 associated to the Sagittarius dwarf spheroidal galaxy
Eugenio Carretta, Angela Bragaglia, Sara Lucatello +5
As part of our on-going project on the homogeneous chemical characterization of multiple stellar populations in globular clusters (GCs), we studied NGC 5634, associated to the Sagi…
The Thirteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-IV Survey MApping Nearby Galaxies at Apache Point Observatory
SDSS Collaboration, Franco D. Albareti, Carlos Allende Prieto +335
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in July 2014. It pursues three core programs: APOGEE-2, MaNGA, and eBOSS. In addition, eBOSS cont…
The Na-O anticorrelation in horizontal branch stars. IV. M22
R. G. Gratton, S. Lucatello, A. Sollima +6
We obtained high-resolution spectra for 94 candidate stars belonging to the HB of M22 with FLAMES. The HB stars we observed span a restricted temperature range (7,800<Teff<11,000 K…
Resolved photometry of Young Massive Clusters in the starburst galaxy NGC 4214
A. Sollima, M. Cignoni, R. G. Gratton +4
We present the results of deep high resolution imaging performed with ACS/HRC@HST in the most active region of the nearby starburst galaxy NGC 4214. We resolved the stellar populat…
An aluminium tool for multiple stellar generations in the globular clusters 47 Tuc and M 4
Eugenio Carretta, Raffaele Gratton, Angela Bragaglia +2
We present aluminium abundances for a sample of about 100 red giant stars in each of the Galactic globular clusters 47 Tuc (NGC 104) and M 4 (NGC 6121). We have derived homogeneous…
