LAMOST DR1&DR2
Searching for Classical Be Stars in LAMOST DR1 [7] 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 CBes with prominent He~I~$\lambda4387$, He~I~$\lambda4471$ and Mg~II~$\lambda4481$ absorption lines, as well as H$\beta$~$\lambda4861$ and H$\alpha$~$\lambda6563$ emission lines. These candidates significantly increases 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 of CBes are in star clusters. These two CBes have ages of 15.8 and 398~Myr, respectively.
NGC 6830
REPORTING OF NEWLY DISCOVERED BE STARS IN THE OPEN CLUSTER NGC6830 (in prep.) ABSTRACT We report 10 newly discovered Be stars in the open cluster NGC6830 with the Hα imaging photometry of the Palomar Transient Factory Survey. Stellar membership of the candidates was verified with photometric and kinematic memberships using 2MASS data and proper motions. The spectroscopic observations were carried out for two objects by the new spectrograph SED-Machine that is mounted on the Palomar 60 inch Telescope. Our preliminary results of the SED-Machine shows strong Hα emission lines, which are further confirmed by the Hiyoyu spectrograph of Lulin One-meter Telescope. Most of the Be stars (9/11) are located in the outer region of the cluster, suggesting gravitational disruption over time could result in this spatial distribution.
NGC 663
SEARCHING FOR Be STARS IN THE OPEN CLUSTER NGC 663[8] ABSTRACT We present Be star candidates in the open cluster NGC663, identified by Hα imaging photometry with the Palomar Transient Factory Survey, as a pilot program to investigate how the Be star phenomena, the emission spectra, extended circumstellar envelopes, and fast rotation, correlate with massive stellar evolution. Stellar membership of the candidates was verified by 2MASS magnitudes and colors and by proper motions (PMs). We discover four new Be stars and exclude one known Be star from being a member due to its inconsistent PMs. The fraction of Be stars to member stars [N(Be)/N(members)] in NGC663 is 3.5%. The spectral type of the 34 Be stars in NGC663 shows bimodal peaks at B0–B2 and B5–B7, which is consistent with the statistics in most star clusters. Additionally, we also discover 23 emission-line stars of different types, including non-member Be stars, dwarfs, and giants.
