The results of spectral observations of the Herbig Ae/Be type star HD 179218 are presented. Two wave-like cycles of variability in the parameters of hydrogen lines Hα and Hβ with a characteristic time of ~ 40 days are revealed. The first wave of va

We present the results of spectral observations of the Herbig Ae/Be star HD179218. We discovered a wave-like variation in the parameters of the Hα line emission component with a typical time scale of about 40 days. The observed wave is characterized
