摘要：
Oe stars are a subset of the O-type stars that exhibit emission lilies from a circumstellar disk. The recent; detection of magnetic fields in some O-type stars suggests a possible explanation for the stability of disk-like structures around Oe stars. According to this hypothesis, the wind of the star is channeled by a, dipolar magnetic field producing a disc in the magnetic equatorial plane. As a test, of this model, we have obtained spectropolarimetric observations of the hottest Galactic Oe star HD 155806. Here we discuss its results and implications.
