By using stellar computed atmospheric models with ATLAS9 and ATLAS12 codes, we compare fluxes in the ultra-violet domain with the one observed in low dispersion mode of the IUE satellite for the star λ Boo. We derive the chemical abundance of zinc and chromium from high dispersion IUE data by applying spectrum synthesis technique.enSpectrumArticle
