The open cluster NGC 2509. Stellar rotation and main sequence turnoff extension from FLAMES spectroscopy
C. Boeche, J. Alonso-Santiago, A. Bragaglia +8
NGC 2509 is a distant (~2.5 kpc) and little-studied open cluster located in the third Galactic quadrant. It is a moderately old cluster, whose age has not yet been precisely determ…
The open cluster King~1 in the second quadrant
R. Carrera, L. Rodríguez Espinosa, L. Casamiquela +4
We analyse the poorly-studied open cluster King~1 in the second Galactic quadrant. From wide-field photometry we have studied the spatial distribution of this cluster. We determine…
New H-band Stellar Spectral Libraries for the SDSS-III/APOGEE survey
O. Zamora, D. A. Garcia-Hernandez, C. Allende Prieto +18
The Sloan Digital Sky Survey--III (SDSS--III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) has obtained high resolution (R 22,500), high signal-to-noise r…
Analysis of the CN and CH molecular band strengths in stars of the open cluster NGC 6791
R. Carrera
Low resolution SDSS/SEGUE spectra have been used to study the behavior of the strengths of the CN and CH molecular bands in stars at different evolutionary stages of the open clust…
Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
E. Pancino, M. Rejkuba, M. Zoccali +1
Globular clusters show abundance variations for light elements that are not yet well understood. The preferred explanation involves a self-enrichment scenario, with two subsequent…
Radial extent of the SGB in NGC 1851
M. Zoccali, E. Pancino, M. Catelan +3
Recent HST-ACS observations revealed the presence of a double subgiant branch (SGB) in the core of the Galactic globular cluster NGC 1851. This peculiarity was tentatively explaine…
