Abstract:
An analysis of the stars included in the catalogue of λ Bootis
stars by Paunzen et al. (1997, Cat. J/A+AS/123/93) and which also
have IUE observations is presented here. Population I A-F type stars
as well as field horizontal branch stars were also included in the
analysis. Using line-ratios of carbon to heavier elements (Al and
Ni) allows us to establish unambiguous membership criteria for the
λ Bootis group.
