Abstract
All the radial velocities (RV) available in the literature since the beginning of the century for the Be stars EW Lac, 28 Tau, ζ Tau, KX And, KY And, CX Dra and 88 Her, are assembled. When possible, a periodogram analysis has been performed to search for eventual periodic phenomena.
The following conclusions have been drawn: EW Lac could be a spectroscopic binary with a period of about 40 years; 28 Tau shows some indications of regular long-term RV variations on the time scale of decades; a probable recurrent shell activity of ζ Tau could be hypothesized. Some useful indications for KX and KY And are given, whereas it is not possible to draw any conclusion for CX Dra and 88 Her owing to the lack of data.
