Six year spectroscopy of V2028 Cyg

The presence of the cold type absorption lines combined with the hot type spectrum indicate a binarity of this object. Since the B[e] stars are embedded in an extended envelope, the usage of common stellar atmosphere models for the analysis is not very appropriate.

Therefore we focus on the analysis of the long term spectral line variations in order to determine the nature of this object. We present time dependencies of the equivalent width and radial velocities of the H{alpha} line, [OI] 6300{AA}, FeII 6427, 6433, and 6456{AA} lines. The bisector variations and line intensities are shown for the H{alpha} line.
