FSR584 - a new globular cluster in the Galaxy?
E. Bica, C. Bonatto, S. Ortolani +1
We investigate the nature of the recently catalogued star cluster candidate FSR584, which is projected in the direction of the molecular cloud W3 and may be the nearest globular cl…
Obscured clusters.I. GLIMPSE30 - Young Milky Way Star Cluster Hosting Wolf-Rayet Stars
R. Kurtev, J. Borissova, L. Georgiev +2
Young massive clusters are perfect astrophysical laboratories for study of massive stars. Clusters with Wolf-Rayet (WR) stars are of special importance, since this enables us to st…
Near-infrared observations of the Fornax dwarf galaxy. I. The red giant branch
M. Gullieuszik, E. V. Held, L. Rizzi +3
We present a study of the evolved stellar populations in the dwarf spheroidal galaxy Fornax based on JHK imaging photometry. The observations cover an 18.5x18.5 arcmin central area…
Na-O Anticorrelation and Horizontal Branches. V. The Na-O anticorrelation in NGC 6441 from Giraffe spectra
R. G. Gratton, S. Lucatello, A. Bragaglia +16
We present an analysis of FLAMES-Giraffe spectra for several bright giants in NGC 6441, to investigate the presence and extent of the Na-O anticorrelation in this anomalous globula…
