5. The line in HD 76932

The 2089.6 Å line was observed in the [Fe/H] thick-disk star HD 76932 by Rebull et al. (1998). The 2089.6 Å feature is strong in that star, actually stronger than expected from the 2497 Å line, even when NLTE corrections are not taken into account. The line position furthermore tends to suggest a ¹¹B-rich feature. Both these findings are opposite to the ones we find for our extreme Pop II star. Rebull et al. suggest that there may be a blending line affecting the 2089.6 Å feature in HD 76932. If that is so, we see no traces of it in HD 140283.
