Abstract

We made detailed abundance analysis for ultimative test of membership of twenty λ Bootis type stars candidates. Atmosphere parameters, LTE abundances for ten elements (including C and O) and NLTE values for Na were determined. We are able to confirm or establish the membership for nine objects (HD 23258, HD 36726, HD 40588, HD 74911, HD 84123, HD 91130, HD 106223, HD 111604 and HD 290799). Six stars (HD 90821, HD 98772, HD 103483, HD 108765, HD 201184 and HD 261904) can be definitely ruled out as being member of the λ Bootis group whereas no ambiguous decision can be drawn for another five stars (HD 66684, HD 105058, HD 120500, HD 141851 and HD 294253). We also tryed to find apparent spectroscopic binaries which have two solar abundant components mimic one metal-weak star as proposed by Faraggiana & Bonifacio (1999).
