Be stars in open clusters. II. Balmer line spectroscopy.

Abstract (from CDS):

We present Hα line profiles (R≃3x103, S/N≃102 at continuum level, ≃50 for some objects) for 58 stars in 8 northern open clusters and associations, complemented with Hβ and Hγ profiles for 36 of them as well as Hδ and Hε for 16 programme stars. Our observations, though lower in resolution, yield results which are in good agreement with those obtained in earlier works based mainly on field Be stars. Our data suggest a similar spectroscopic behavior for both field and cluster Be stars. The line parameters (EW, FWHM, {DELTA}vp) have been obtained for each line. Nearly the whole set of stars have previously published quasi-simultaneous uvbyβ photometry, so a study of reliable correlations between photometric and spectroscopic data can be undertaken.
