cds-question@unistra.frsurveysbe-starsWe report on searching for Classical B-type emission-line (CBe) stars in the first data release of the Large Sky Area Multi-Object fiber Spectroscopic Telescope (LAMOST; also called the Guo Shou Jing Telescope). A total of 192 objects (including 12 previously known CBes) were identified as CBe candidates with prominent HeI {lambda}4387, HeI {lambda}4471 and MgII {lambda}4481 absorption lines, as well as H{beta} {lambda}4861 and H{alpha} {lambda}6563 emission lines. These candidates significantly increase the currently known sample of CBes by about 8%. Most of the CBe candidates are distributed near the Galactic Anti-Center due to the observing strategy used for LAMOST. Only two CBes are in star clusters. These two CBes have ages of 15.8 and 398Myr, respectively.2015RAA....15.1325Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/15.1325CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/146 : LAMOST DR1 catalogs (Luo+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/15.1325https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/15.1325http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/15.1325https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/15.1325https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/15.1325http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/15.1325GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/15.1325/table2 (23 Known CBes Found in LAMOST DR1)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/15.1325/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/15.1325/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/15.1325/table2?GETtext/xml+votable180.050000true98.2473754.93958330.005555555555555556Cone search capability for table J/other/RAA/15.1325/table3 (CBe Candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/15.1325/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/15.1325/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/15.1325/table3?GETtext/xml+votable180.050000true67.8802547.96408330.0055555555555555566/862 1289 1296 1309-1310 1318 1328-1329 1429 1466 1733 1741 1830 1848 1945 2155 2623 2666 2705 2717 9074 21943 22171 22236 22243 22249 22252 22254 22256 22260 23829 23905 24153 24375 24382 24384 24457 24466-244671.1166583743361574e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/15.1325?format=asciidefaultJ/other/RAA/15.1325/table223 Known CBes Found in LAMOST DR1recnoRecord number assigned by the VizieR team.
