We performed an elemental abundance analysis using a high dispersion spectrum in the optical region, and confirmed its mild metal underabundance. In our discussion we reinforce the suggestion that Vega is a mild lambda Boo star.","authors_text":"D. Dominis, K. Pavlovski (University of Zagreb), M. Planinic, M. Rosandic, S.
