Sažetak
Since Baschek and Slettebak (1988) drew attention to the similarity between the abundance pattern of Lambda Boo stars and that of Vega, there has been a long debate whether Vega should be listed among the chemically peculiar stars of Lambda Boo type. 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.
