HII emission from a complete spectroscopic survey of Be stars in h and χ Persei

We describe data for emission-line B stars observed in a spectroscopic survey of h and chi Persei. The survey is complete to V = 12.5 and covers an area of similar to1100 arcmin(2) roughly centered on the two clusters. We detect 32 Be stars; some have low Halpha emission strength. Seven of these are new identifications; seven others are confirmations of Be stars previously identified using photometry. Five of the observed Be stars show significant Halpha profile variations from epoch to epoch. We show that spectral indices yield physical characteristics of the H II emission region. This automatic method is robust and easily applied to large spectroscopic samples. We infer Halpha : Hbeta flux ratios of 2-5 and observe a linear relationship between Halpha emission and J-K color for these stars. We include a Hertzsprung-Russell diagram for the B-type stars in the clusters.
