About article:
We show that high-resolution observations of resolved Zeeman split
lines can be used to obtain new constraints on the stellar magnetic field
geometry. In
particular, the contrast of the field strength distribution over the stellar
surface can be deduced from differential measurement of the second moment
of the π and σ Zeeman components. Our analysis
of the triplet lines in slowly rotating cool
magnetic CP stars uncovers a surprisingly homogeneous field structure,
inconsistent with any low-order multipolar geometry.
