Open clusters as key tracers of Galactic chemical evolution. III. Element abundances in Berkeley 20, Berkeley 29, Collinder 261, and Melotte 66
P. Sestito, A. Bragaglia, S. Randich +3
Galactic open clusters are since long recognized as one of the best tools for investigating the radial distribution of iron and other metals. We employed FLAMES at VLT to collect U…
X-shooter: a medium-resolution, wide-band spectrograph for the VLT
L. Kaper, S. D'Odorico, F. Hammer +2
X-shooter is the first second-generation instrument for the ESO Very Large Telescope and will be installed in 2008. It is intended to become the most powerful optical & near-infrar…
Lithium depleted stars in the young sigma Ori cluster
G. G. Sacco, S. Randich, E. Franciosini +2
Context: Knowledge of the age distribution of stars in young clusters and associations is crucial to constrain models of star formation. HR diagrams of different young clusters and…
Element abundances of unevolved stars in the open cluster M 67
S. Randich, P. Sestito, F. Primas +2
We determined the metallicity ([Fe/H]), together with O, Na, Mg, Al, Si, Ca, Ti, Cr and Ni abundances for a sample of 10 unevolved or slightly evolved stars belonging to the open c…
XMM-Newton observations of the sigma Ori cluster. II. Spatial and spectral analysis of the full EPIC field
E. Franciosini, R. Pallavicini, J. Sanz-Forcada
We present the results of an XMM-Newton observation of the young (~2-4 Myr) cluster around the hot star sigma Orionis. In a previous paper we presented the analysis of the RGS spec…
Age spreads in star forming regions: The lithium test in the Orion Nebula Cluster
F. Palla, S. Randich, E. Flaccomio +1
We present the initial results of a study of the surface lithium abundance in a sample of low-mass members (M~0.4-1.0 Msun) of the Orion Nebula Cluster (ONC) that provide an indepe…
