Abstract:
The literature on the λ Boo stars has grown to become somewhat
heterogenous, as different authors have applied different criteria
across the UV, optical and infrared regions to determine the
membership status of λ Boo candidates. We aim to clear up the
confusion by consulting the literature on 212 objects that have been
considered as λ Boo candidates, and subsequently evaluating the
evidence in favour of their admission to the λ Boo class. We
obtained new spectra of ∼90 of these candidates and classified them on
the MK system to aid in the membership evaluations. The re-evaluation
of the 212 objects resulted in 64 members and 103 non-members of the
λ Boo class, with a further 45 stars for which membership
status is unclear. We suggest observations for each of the stars in
the latter category that will allow them to be confidently included or
rejected from the class. Our reclassification facilitates homogeneous
analysis on group members, and represents the largest collection of
confirmed λ Boo stars known.
Description:
Membership evaluations for 212 lambda Boo candidates in the
literature. For each star a transverse has been calculated from SIMBAD
parallaxes and proper motions. V, B-V and vsini values are also
collated.
