Time-dependent spectral-feature variations of stars displaying the B[e] phenomenon: I. V2028 Cyg
Original language description
We present results of nearly six years of spectroscopic observations of the Be star V2028 Cyg. The presence of the cold-type absorption lines combined with a hot-type spectrum indicate the binarity of this object. Since B[e] stars are embedded in an extended envelope, the usage of common stellar atmosphere models for the analysis is quite inappropriate. Therefore, we focus on the analysis of the long-term spectral line variations in order to determine the nature of this object.
