Searching for Classical Be Stars in LAMOST DR1 [http://adsabs.harvard.edu/abs/2015arXiv150507290L]
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.

REPORTING OF NEWLY DISCOVERED BE STARS IN THE OPEN CLUSTER NGC6830 (in prep.)
ABSTRACT
We discovered 2 new Be stars, and re-identified one known Be star in the open
cluster NGC 6830. Eleven Hα emitters were discovered using the Hα imaging
photometry of the Palomar Transient Factory Survey. Stellar membership of the
candidates was verified with photometric and kinematic information using 2MASS
data and proper motions. The spectroscopic confirmation was carried out by using
the Shane 3-m telescope at Lick observatory. Based on their spectral types, three
Hα emitters were confirmed as Be stars with the Hα equivalent widths > −10A.
Two objects were also observed by the new spectrograph SED-Machine on the
Palomar 60 inch Telescope. The SED-Machine results show strong Hα emission
lines, which are consistent with the results of the Lick observations. The high
efficiency of the SED-Machine can provide rapid observations for Be stars in a
comprehensive survey in the future.

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.

REPORTING OF NEWLY DISCOVERED BE STARS IN THE OPEN CLUSTER NGC6830 (in prep.)
ABSTRACT
We discovered 2 new Be stars, and re-identified one known Be star in the open 
cluster NGC 6830. Eleven Hα emitters were discovered using the Hα imaging 
photometry of the Palomar Transient Factory Survey. Stellar membership of the 
candidates was verified with photometric and kinematic information using 2MASS 
data and proper motions. The spectroscopic confirmation was carried out by using 
the Shane 3-m telescope at Lick observatory. Based on their spectral types, three 
Hα emitters were confirmed as Be stars with the Hα equivalent widths > −10A. 
Two objects were also observed by the new spectrograph SED-Machine on the 
Palomar 60 inch Telescope. The SED-Machine results show strong Hα emission 
lines, which are consistent with the results of the Lick observations. The high 
efficiency of the SED-Machine can provide rapid observations for Be stars in a 
comprehensive survey in the future.

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.
