Thirty of the 70 stars varied in their shell characteristics between the two epochs. The total number of stars whose Hα line var

I shall also attempt to incorporate the results of the speakers who follow in this session, in order to save duplication of individual introductions and allow the later presentations to concentrate more on the relevant discussions. I shall deal with nine aspects of Be stars behaviour, under the headings below.

https://doi.org/10.1007/978-94-007-6314-2g Ca II triplet emission without H and K emission is discussed. The implications of this phenomenon on the structure of Be envelopes and possibly the binary nature of some Be stars is discussed..Evidence indicating the presence of cool companions to the Be stars HD 218393 and HR 894 is presented.
