Aims. We spectroscopically characterize the Galactic Bulge to in fer its star formation timescale, compared to the other Gala ctic components, through the chemical signature on its individual stars. Methods. We derived iron and oxygen abundances for 50 K giants in four fi elds towards the Galactic bulge. High resolution (R =45,000) spectra for the target… CONTINUE READING
