https://doi.org/10.1007/978-3-031-05328-3The early history of the studies on Be stars is reviewed. The importance of keeping in mind a basic model of a Be star is emphasized, and the binary star model is suggested as one serious possibility at least for some Be stars.

https://doi.org/10.1007/978-1-4613-2823-0The appearance of singly ionized iron emission lines in the spectra of early type stars is studied, and the results of a spectroscopic investigation of EW Lac and other Be stars are given. We also discuss the atomic processes of excitation of Fe ti in the stellar envelopes using a two-parameter diagram W, ......

Rapid Variations of H, in Be StarsPhotoelectric spectrum scans of Be stars were analysed to study the short-term variations of H. emission strengths. In . Tau, . Col, PP Car, and . Cen, definite variations of a few percent with time scales of 1 to 3 minutes were found. These variations do not exhibit any periodicity.
