We have studied variability of the spectral lines of the OB star delta Ori A -the brightest component of the delta Ori triple system. ... However, some of the variable features go outside the band, presumably due to either imhomogeneities in the stellar wind from .Ori Aa1 or non-radial pulsations of the weaker components of the system, Aa 2 or Ab. ...

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...
