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

Young stars in which subsoil processes of thermonuclear synthesis and which shine at the expense of the continuing gravitational compression haven't begun yet are one of the astrophysics objects which are most actively investigated today. It is cause

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
