Emerging Flux Simulations and Proto-Active Regions

Robert F. Stein, Anders Lagerfjärd, Åke Nordlund, Dali Georgobiani

摘要:

最小结构(均匀和水平)磁场从20微米的深度的出现进行了模拟。电场首先以混合极性的胡椒和盐的形式出现,但随后聚集成单独的单极浓度并产生孔隙。然后人为地增加场强以产生点状结构。在连续光学深度单位处的场强峰值为1 kG,最大值为4 kG。在垂直磁场很强的地方,这些斑点会持续存在(目前已经模拟了一个小时的太阳时)。在磁场弱的地方,斑点被填满并消失。采用Hinode环形调制传递函数、狭缝衍射和频率平滑等方法计算并处理了斯托克斯轮廓。这些数据可在steinr.pa.msu.edu/~bob/stokes上查阅。

英文摘要:

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 mtf, the slit diffraction and frequency smoothing. These data are available at steinr.pa.msu.edu/~bob/stokes.
