C, N, O in λ Boo stars and in composite spectra.

FARAGGIANA R. and BONIFACIO P.

Abstract (from CDS):

The selective abundance of C, N, O (almost solar) with respect to that of other elements (underabundant) in λ Boo stars has been interpreted as a characteristic peculiarity of these objects, when considered as single stars. We show here that a similar selective abundance is predicted from the composite spectra resulting from two unresolved stars in the same temperature range as the λ Boo stars.
