Beginning of ReadMe : J/other/PASA/32.36 lambda Boo star membership evaluations (Murphy+, 2015) ================================================================================ An evaluation of the membership probability of 212 lambda Boo Stars. I. A Catalogue. Murphy S.J., Corbally C.J, Gray R.O., Cheng K.-P., Neff J.E., Koen C., Kuehn C.A., Newsome I., Riggs Q. <Publ. Astron. Soc. Australia, 32.36 (2015)> =2015PASA...32...36M (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Stars, peculiar ; Stars, early-type ; Rotational velocities Keywords: stars: chemically peculiar - stars: early-type - stars: abundances Abstract: The literature on the lambda 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 lambda Boo candidates. We aim to clear up the confusion by consulting the literature on 212 objects that have been considered as lambda Boo candidates, and subsequently evaluating the evidence in favour of their admission to the lambda 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 lambda 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 lambda 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.
