Pleione is a classical Be star well known for its cyclic transitions between Be-, shell- and normal B spectral phases. Its nature as a binary system was discussed by McAlister et al. (1989), Gies et al. (1990), Luthardt & Menchenkova (1994) and Nemravova et al (2010). We present the results that trace the evolution of the dimensions of the circumstellar disk of Pleione that are related to the binary system.
