Abstract:
We have performed linear polarization observations of the WR+O binary systems HD 94305 and HDE 320102 with the VATPOL photopolarimeter attached to the 2.15-m telescope in CASLEO, San Juan, Argentina. Both binary systems show phase-locked variations in their polarization. Analysis of these variations in the framework of the binary model yields rather high orbital inclinations for both systems. This is in conflict with the expected mass-value for the O-type component in HD 320102. We postulate an extra contribution for the polarization due to the winds of the binary components. © Universidad Nacional Autónoma de México.
