Spectropolarimetric Signatures of Down-flows About Magnetic Boundaries
Abstract
We analyze spectropolarimetric signatures across magnetic boundaries of opposite polarities at the photosphere. HAO/NSO Advanced Stokes Polarimeter measurements were made at the NSO/Dunn Solar Telescope of photospheric spectral lines (FeI 6301.2 A and 6302.3 A). These observations (NOAA 9662; 2001 October 16-17) about a corridor of a magnetic inversion line near the edge of a disk-center sunspot show strong red-asymmetry. Several (at least six) such discrete and compact sites of both polarities, near these magnetic neural lines, show such red-asymmetry. Strong down-flows associated with these unusual Stokes polarization profiles are associated with these asymmetries. We discuss detailed properties and possible origin of the observed profiles.
