How many λ Bootis stars are binaries?


Abstract (from CDS):

In the attempt to shed new light on the λ Boo phenomenon we analyzed the astrometric, photometric and spectroscopic characteristics of stars out of a list of recently selected λ Boo candidates. We show that the class is still ill-defined and discuss the possibility that some, if not most stars presently classified as λ Boo, are in fact binary pairs and that peculiar abundances may not correspond to actual values if the average values of the atmospheric parameters Teff and logg are assumed and the effect of veiling is not taken into account.
