Part of the Lecture Notes in Physics book series (LNP, volume 193)


Observations of Betelgeuse's optical continua linear polarization are reviewed. Arguments are presented that the observed ordered large-scale polarization variations emanate from this star's lower atmosphere, i.e., at or near the photosphere. Polari zation-producing mechanisms are indicated, the most promising being large-scale surface convective features.
