Campaign Periastron Passages of Pleione
VV Cep up-to-date: 2019-09-20
The current state of the ARAS campaign observation results seems to explain the periodic time behavior of the equivalent width EW and the flux of the Hα emission components V&R.
Based on these results, a new geometric structure of the emission sources has been developed in collaboration with Prof. Dr. Ph. Bennett (Dalhousie University, Halifax, NS, Canada).
