Abundances in the galactic spheroid from UVES spectra

摘要

We present early results on stars of the galactic spheroid obtained using UVES, the cross dispersed echelle spectrograph of VLT. Within its two first years of operation, UVES has already allowed major progresses in our views of the early galactic spheroid, including significant improvements in the age estimates and a deeper insight into the processes that lead to metal-enrichment in the Galaxy. Perspectives for the next few years, with the possible use of the multiobject fiber facility FLAMES coupled with both UVES and the new Giraffe spectrographs are briefly outlined
