| Abstract: |
Results from the quantitative spectroscopy of B-stars in the Galaxy are discussed with reference to its present chemical composition as a function of galactocentric radial distance. Preliminary results from a differential non-LTE abundance analysis of B-supergiants in the Galaxy, the LMC and the SMC are presented. For the LMC these results indicate moderate deficiencies (relative to the Galaxy) in O accompanied by similar deficiencies for Mg and Si. The results for the SMC are qualitatively the same but here the deficiencies are much greater, approximately a factor of 40 for O. |
