18 May 1998 | Subject: | astro-ph | Affiliation: | University of Zagreb | Abstract: | Since Baschek & 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. | Source: | arXiv, astro-ph/9805234 | Services: | Forum | Review | PDF | Favorites |
