| Abstract: |
The nitrogen abundance-age relation for main-sequence early B-stars is examined by extending the study by Gies and Lambert of the C, N, and O abundances in a sample of early B-stars. Nitrogen enrichment is observed during the MS phase, which is about 0.4 dex for stars with mean mass of 10.3 solar masses and almost 0.6 dex for stars with 12.5 solar masses. Both the correlation with age and the dependence on mass are confirmed. |
