Abstract (from CDS):

We present the results of high-resolution spectroscopic observations of the pre-main-sequence (PMS) Herbig Be star HD 200775 obtained between August 1994 and December 1999. The behaviour of Hα, Hβ and He i before, during, and after the last high-activity event of the object in 1997 is studied. A complex picture of the circumstellar evolution in this period is discussed. It is concluded that the results of observations can be interpreted in the framework of a model with a variable stellar wind originating from the star. We emphasize the importance of coordinated high-resolution spectroscopic observations for further understanding the star's behaviour.
