Abstract:
We have derived the chemical composition of nine UV-bright stars
belonging to five Galactic globular clusters of various metallicities
([Fe/H] from -1.0 to -2.4dex). The analyses are based on high
resolution spectra obtained with the UV-Visual Echelle Spectrograph
(UVES) at VLT-UT2.
Description:
The spectra were obtained with the UVES spectrograph attached to the
second VLT unit from April to September 2002 (program ID 69.D-0081).
