| Abstract: |
The emergence of minimally structured (uniform and horizontal)
magnetic field from a depth of 20 Mm has been simulated. The field
emerges first in a mixed polarity pepper and salt pattern, but then
collects into separate, unipolar concentrations and produces pores.
The field strength was then artificially increased to produce
spot-like structures. The field strength at continuum optical depth
unity peaks at 1 kG, with a maximum of 4 kG. Where the vertical field
is strong, the spots persist (at present an hour of solar time has
been simulated). Where the field is weak, the spot gets filled in and
disappears. Stokes profiles have been calculated and processed with
the Hinode annular Modulation Transfer Function, the slit diffraction,
and frequency smoothing. These data are available at steinr.pa.msu.edu/∼bob/stokes. |
