Abstract

Spectra in the range 4000-7000 Å were obtained for a sample of bulge stars using the GMOS-Gemini low resolution spectrograph. The sample stars were selected from a VLT-FLAMES project for the observation of 1000 bulge stars, for which abundance ratios have been derived. Our aim is to study old stellar populations in external galaxies.
