Résumé

The results of observations of polarization for the Be star ? And that are given are in fully satisfactory agreement with the results obtained by Arsenijevic, Vince, and Kubicela in 1974-1977. All these observations together support Harmanec's hypothesis that strengthening of the circumstellar envelope of ? And occurs during periastron passage of its companion, moving in an elongated orbit with a period of 8.5 years. The results of polarimetric observations of LZ Cep indicate that its slight, variable intrinsic polarization may originate, as in most semidetached systems, in the scattering of radiation of these stars from particles of matter escaping from the component that is filling its Roche lobe.
