Scientific paper

From 1978 December to 1979 May, we made spectrographic observations of φPer, ζTau and κDra using our 60/90 Schmidt cassegrain grating spectrograph. Values of electron density, rotational speed and V/R variation have been obtained and a comparison between ζTau and the supergiant βOri carried out. We found that, over our observed period, θPer showed clear shell activities, ζTau was in a relatively calm phase, its shell slowly expanding, while κDra had all the signs of a ``classical'' Be star.
