Searching for classical Be stars in LAMOST DR1

发布时间：2019-03-11 10:10

【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.

A total of 192 objects (including 12 previously known CBes) were identified as CBe candidates with prominent He I 位 4387, He I 位 4471 and Mg II 位 4481 absorption lines, as well as H 尾 位 4861and H 伪 位 6563 emission lines.
