| 英文摘要 | We report the discovery of two new Be stars, and re-identify one known Be star in the open cluster NGC 6830. Eleven H alpha emitters were discovered using the H alpha 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 the Lick observatory. Based on their spectral types, three Ha emitters were confirmed as Be stars with Ha equivalent widths greater than -10 angstrom. Two objects were also observed by the new spectrograph spectral energy distribution-machine (SED-machine) on the Palomar 60-inch Telescope. The SED-machine results show strong Ha 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. |
