Spectral variability of IL cephei

The results of six years of spectroscopic studies of the Herbig Be star IL Cep (HD216629) are reported. Various spectral parameters of the H α and H β emission lines and those of the He I λ 5876 Å absorption feature are found for the first time to have exhibited slow variations in 2006–2011 and to have reached their extrema in 2009–2010. The Na I D1 and D2 lines reproduce, in a weaker form, the H α radialvelocity variations. It is suggested that the variations found in the spectrum of the star may be due to the presence of additional bodies in the system.
