描述Ten years after the ?rst ESO Workshop on light elements, and ?ve years after the IAU in conference in Natal (Brazil) on the same subject, we felt that it was time to have a new conference on this topic: a wealth of new observational data have become available from the 8-meter telescopes and in particular from the VLT, and, at the same time, in the last years new theoretical roads have also been inaugurated in the interpretation of the stellar data. It soon became clear, on the other hand, that in order to understand the evolution of the fragile Li and Be in stars and in the Galaxy, the whole problem of internal mixing in stars must be addressed and understood ?rst, and therefore a large number of elements must be investigated, in many di?erent environments. Adding to this general context the fact that the FLAMES facility at the VLT was o?ered to the community one year earlier, and that it was starting to produceanimpressivewealthofabundancedataofstarsintheGalaxyandinour neighborhoods, the broad concept of the ESO–Arcetri workshop on “Chemical Abundances and Mixing in Stars in the Milky Way and its Satellites” was built. The location had to be in our beloved Toscana, and Castiglione

Old Open Clusters as Tracers of Galactic Chemical Evolution: the BOCCE Projectmass stars and as tracers of the Galactic disk properties. Since old OCs allow us to probe the lifetime of the Milky Way disk, up to about 10 Gyr ago, they can be used to study the disk evolution withtime, and in particular its chemical history.

Chemical Abundances and Mixing in Red Clump Stars of the Galaxyand abundances of .C, .C, N, O and other mixing sensitive chemical elements were investigated. Elemental ratios in the sample of field stars are compared to the results available for evolved stars in open clusters and to the theoretical prediction of extra mixing in stellar interiors.

Abundance Trends in the Thin and Thick Diskssurge of studies of the elemental abundance trends in the disks using high resolution spectroscopy. Here I will review and discuss the currently available data. Special focus will also be put on how we define stars to be members of either disk, and how current models of galaxy formation favour that

On the Chemical Abundances of Stars with Giant Planetshese were found to have, on average, a metal content higher than the one found in stars without detected planetary companions. In this contribution we will mainly focus on the most recent results on the chemical abundances of planet-host stars, and what kind of constraints they are bringing to the t

Observational Constraints on Nucleosynthesis in AGB Starsspite the uncertainties still existing in the chemical analysis of these stars, the determination of the abundances of several key species in their atmospheres (lithium, s-elements, carbon and magnesium isotopic ratios etc.) is an useful tool to test these theories and the mixing processes during th

A Comparison of Methods for Photospheric Abundance Determinations in K-Type Starsiques and compared the results obtained in order to establish their respective merits and faults. The two spectroscopic methods give consistent results suggesting that non- LTE effects are small, whereas the ‘mixed’ spectroscopic-photometric method leads to photospheric parameters and abundances sys

NGC2324: A Relatively Young, Metal-Poor Open Cluster Located Beyond the Perseus Spiral Armtic anticentre direction. We believe that the high discrepancy in the basic cluster parameters derived in previous studies, particularly in the cluster metal content, warrants their redetermination on the basis of more reliable data.
