On the structure of the sunspot magnetic field deduced from broadband circular polarization
Abstract
The characteristics of the broad-band circular polarization of sunspots are confirmed for sunspots of the new solar cycle. It is stronger on the limb-side of sunspots and its polarity is always positive (negative) for S (N) magnetic polarity in three recent solar cycles. The sunspot model of an unwinding emerging magnetic field proposed in the previous analysis is illustrated.
