摘要： We 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 He I λ4387, He I λ4471 and Mg II λ4481 absorption lines, as well as Hβλ4861and Hαλ6563 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 398 Myr, respectively. 其他題名： Chinese Journal of Astronomy and Astrophysics 出版者： National Astronomical Observatories of Chinese Academy of Sciences and IOP Publishing 出版日期： 2015-08-01 出處： Research in astronomy and astrophysics, 2015-08, Vol.15 (8), p.1325-1331 資源來源： Institute of Physics Journals 版權： 2015 National Astronomical Observatories, Chinese Academy of Sciences and IOP Publishing Ltd 識別號： ISSN: 1674-4527 識別號： ISSN: 2397-6209 識別號： EISSN: 2397-6209 識別號： DOI: 10.1088/1674-4527/15/8/015
