Lambda Bootis Stars

The Lambda Bootis stars are a class of metal-weak, Population I A-type stars, first discovered by Morgan et al. (1943). These stars are metal deficient (by up to -2 dex in the most extreme cases), but have nearly solar abundances of C, N, O, and S. About 35 Lambda Bootis stars are now known.
