Investigations concerning the stellar and the interstellar component of the polarization of star light
Abstract
A study is conducted of the polarization of star light in the case of Be stars, Me stars, and supergiant stars. The light of all stars is polarized by the interstellar dust. It is found to be practically impossible to separate the contribution made by the interstellar dust to the polarization from the polarization present in the radiation at the source of emission. The rather high polarization level often observed in the case of the light emitted by Mira-type stars can be explained on the basis of a circumstellar envelope of dust which is expelled at the point of eruption of every period after the minimum. Typical polarization characteristics found in the study of Be stars are also discussed.
