摘要:
AbstractThe time dependent polarization of the light of some red long period variables can be explained using the simple model of the oblique rotator. Near the magnetic poles the dust particles in the outer layers of the stellar atmosphere could be aligned in the magnetic field by the Davis‐Greenstein mechanism. For the stars V CVn, L2Pup, R Leo, and R Peg the spatial orientation of the rotational axis, the angle between the magnetic poles and the rotational axis and the period of the revolution of the magnetic poles around the rotational axis were derived from the observational material. The proposed hypothesis gives an explanation of the essential observational facts concerning the intrinsic polarization of some of the red variable
