Spectra of bulge giants for population synthesisB. Barbuy, A. Alves-Brito, S. Ortolani, M. Zoccali, D. Minniti
We present medium-resolution spectra, obtained with GMOS-Gemini, for giants in the Galactic bulge. These giants were also observed at high resolution with Flames and UVES, and analysed. Therefore we have their abundance ratios in particular Mg/Fe, O/Fe, Ca/Fe, Ti/Fe ratios, which make them particularly useful for population synthesis.
