| Abstract: | High-resolution spectroscopy during the eclipse of EE Cep was obtained and presented for the first time. The star’s spectroscopic
behaviour can be roughly interpreted as a partial eclipse of the high luminosity Be primary and its emitting gaseous ring
by the semi-transparent gaseous envelope around an invisible, opaque secondary, most probably a dark disk.
This paper is based on spectroscopic observations from Asiago (Italy), DDO (Canada), Rozhen (Bulgaria), SPM (Mexico), Terskol
(Russia) and Torun (Poland) observatories. |
