Abstract: The Hanle Effect is a weak Zeeman effect that applies to resonance line scattering and operates in the range of 1–300 Gauss. So far, it has been used only in solar astrophysics. In this paper, we describe how the Hanle effect might be used to measure circumstellar magnetic fields in hot stars by presenting models and simulated data of polarimetric profiles of stellar wind lines.
