| Abstract: |
This is a preliminary report on abundances for two red giants each in the young globular clusters Ruprecht 106 and Pal 12. For Rup 106, we find [Fe/H] = -1.50 but almost all other elements are more deficient than iron, in reverse of the pattern in most metal-poor stars; the exception is oxygen, with [O/Fe] =~ 0.0. Pal 12 is less depleted, with [Fe/H] = -1.0, and has more nearly solar abundance ratios; we have no data on oxygen in Pal 12. |
