cds-question@unistra.frpeculiar-variable-starsearly-type-starsThe 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.2015PASA...32...36Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PASA/32.36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/PASA/32.36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/PASA/32.36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/PASA/32.36https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/PASA/32.36https://vizier.iucaa.in/viz-bin/votable?-source=J/other/PASA/32.36http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/PASA/32.36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/PASA/32.36/lb_evals (Membership evaluations and parameters for 212 lambda Boo candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/PASA/32.36/lb_evals?https://vizier.iucaa.in/viz-bin/conesearch/J/other/PASA/32.36/lb_evals?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/PASA/32.36/lb_evals?GETtext/xml+votable180.050000true1.290660645.22903080.0055555555555555566/172 408 451 603 666 811 1114 1169 1545 1885 1989 2456 2675 2731 2747 2872 3027 3054 3231 3377 3420 3810 3849 4115 4206-4207 4249 4277 4687 4699 4720 4858 5171 5253 5311 5318 5428 5446 5501 5608 5762 5781 5872 6442 7269 7504 8494 8790 9125 9310 9995 10420 10459 10472 10695 10804 10900 10990 11851 12918 13001 13474 13646 13723 13992 14224 14575 14640 14643 14652-14653 14906 15437 15472 15702 16104 16204 16543 16629 16703 17112 18431 19025 19099 19329 20125 20184 21099 21399 21439 21538 22850 22852 22861 22884-22885 23001 23040 23375 23408 23637 23662 23717 23785 23898 24404 24512 24839 25282 25455 25963 26310 26434 26446 26465 27322 27577 27735 27826 27895 27906 27909-27910 27956 28019 28039 28062 28172 28486 28518 28521 28737 28762 28994 29086 29428 29519 30221 30229 30261 30467 30507 30580 30851 31259 31284 31776 31790 31928 32065 32202 33117 33469 34680 35104 35132 35823 36149 36298 36341 37055 37186 37758 37842 37916 38238 38812 39228 39263 39596 39765 40029 40345 41424 41427 41460 41613 42328 42375 42421 42618 42644 42913 42918 43009 43481 43557 44258 44362 44499 45643 45835 45928 46138 46234 46979 47110 47357 47409 47520 47760 47876 48299 48546 48874https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/PASA/32.36?format=asciiOpticaldefaultJ/other/PASA/32.36/lb_evalsMembership evaluations and parameters for 212 lambda Boo candidatesrecnoRecord number assigned by the VizieR team.
