O článku:
It is still a matter for some debate whether the group
of λ Bootis
stars has been homogeneously defined. A widely discussed working hypothesis
postulates that two solar-abundant stars of an undetected spectroscopic binary
system would mimic a single, metal-weak spectrum, thus preventing any reliable
analysis of the group characteristics. Using the newest available
stellar-atmosphere models and synthesis codes, we investigate whether the
proposed spectroscopic-binary model can explain both the observed abundance
patterns and the photometric metallicity indices, and what would be the
percentage of undetected spectroscopic binary systems.
