Computation and Observation of Zeeman Multiplet Polarization in Fraunhofer Lines. III: Magnetic Field Structure of Spot Mt. Wilson 18488

摘要: From an analysis of Stokes parameter profiles measured in a unipolar sunspot, properties its large-scale magnetic field structure have been derived. With due allowance for our present knowledge about the Wilson effect and height line formation, expression strength distribution H(r, z) has obtained. The corresponding gradient equals ∂H/∂z = - 1.5 G km−1 at z 300 km, it increases with decreasing vice versa. inclination vector from ψ 0 ° r to 90 penumbra-photosphere border, variation across spot is not consistent purely radial (poloidal) field. azimuth determined sunspot diameter on several days Macaluso-Corbino effect, significant azimuthal components Hχ found especially umbra.
