Abstract:
We report on abundances of O, Mg, Si, Ca and Fe for 10 giants in the
Sgr dwarf spheroidal derived from high resolution spectra obtained
with UVES at the 8.2m Kueyen-VLT telescope. The iron abundance spans
the range -0.8≲[Fe/H]≲0.0 and the dominant population is relatively
metal-rich with [Fe/H]~-0.25.
Description:
Table 2 contains atomic data and equivalent widths for the lines used
to determine abundances.
Table 3 contains the coordinates and atmospheric parameters
