Ground-based CCD astrometry with wide field imagers. III. [email protected] proper-motion catalog of the globular cluster omega Centauri

A. Bellini, G. Piotto, L. R. Bedin +6

Omega Centauri is the most well studied Globular Cluster because of its numerous puzzling features. Intensive spectroscopic follow-up observing campaigns targeting stars at differe…

The Metal Content of Bulge Field Stars from FLAMES-GIRAFFE Spectra. I. Stellar parameters and Iron Abundances

M. Zoccali, V. Hill, A. Lecureur +5

We determine the iron distribution function (IDF) for bulge field stars, in three different fields along the Galactic minor axis and at latitudes b=-4 deg, b=-6 deg, and b=-12 deg.…

The embedded cluster DBSB48 in the nebula Hoffleit18: comparison with Trumpler14

S. Ortolani, C. Bonatto, E. Bica +2

We derive fundamental parameters of the embedded cluster DBSB48 in the southern nebula Hoffleit18 and the very young open cluster Trumpler14, by means of deep JHKs infrared photome…

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…
