Scientific paper

The star formation history of a given population remains imprinted in the chemical distributions of the their individuals. The parallel study of stellar abundances and nucleosynthesis helps to understand the production of the elements inside stars and their evolution in the interestellar medium. In the present paper copper and zinc abundances of a sample of bulge-like stars are inferred and compared to samples of the solar vicinity. A disk-like distribution of [Zn/Fe] is found for the bulge-like stars, while underabundant [Cu/Fe] ratios relative to disk samples are determined.
