J/A+A/331/633 J/A+A/331/633 IUE spectra of lambda Boo stars E Solano E Paunzen Astron. Astrophys. 331 633 1998 1998A&A...331..633S J/A+AS/123/93 : Lambda Boo stars consolidated catalogue (Paunzen+ 1997) Spectra, ultraviolet Stars, early-type Stars, peculiar stars: chemically peculiar stars: early-type ultraviolet: stars An analysis of the stars included in the catalogue of {lambda} 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 {lambda} Bootis group.
