 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.

 SEARCHING FOR Be STARS IN THE OPEN CLUSTER NGC 663[http://adsabs.harvard.edu/abs/2015AJ....149...43Y]
 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.
