Optical Polarimetry of WR 1 Consistent with a CIR and 17 days Rotation.

Abstract (from CDS):

New visible-band linear polarimetry of the star WR 1 (HD 4004) is presented. This early N-rich Wolf-Rayet star has previously been reported as harboring a Corotating Interaction Region structure threading its wind, implying a stellar rotation period of 16.9 days. Polarization measurements in the Q - U diagram obtained over a span of more than 5 weeks with sampling every few days are revealing (a) variability consistent with the previously reported period and (b) a loop morphology consistent with theoretical models.
