Photospheric Magnetoconvection

该项目将使用磁图和滤波图序列来导出磁通量集中位移的流动图和时间历史。 此外，PI将研究通量在几个超颗粒及以下尺度上在太阳表面的扩散，特别是流对场的反应。 中心目标是找到一个合适的模型来描述与光球磁通量相关的传输现象。 具体来说，PI希望获得的扩散系数的差异，从经典的随机游走的偏差，并依赖于当地的平均磁通量密度的流型的理解。 该项目将结合联合收割机高分辨率数据，以便能够详细研究亚弧秒拓扑结构和通量动态，并利用具有大视野的不间断长时间序列，对通量位移历史进行统计研究。 该计划将提供一种系统和连贯的分析手段，特别侧重于磁对流。

This project will use magnetogram and filtergram sequences to derive flow maps and time histories of displacements of concentrations of magnetic flux. In addition, the PIs will study the dispersal of flux over the solar surface on scales of several supergranules and below, particularly the reaction of flows to the presence of fields. The central goal is finding an appropriate model to describe the transport phenomena associated with photospheric magnetic flux. Specifically, the PIs hope to gain understanding of the differences in the diffusion coefficients, to the deviations from classical random walk, and to the dependence of the flow pattern on the local mean magnetic flux density. The project will combine high-resolution data to allow a detailed study of subarcsecond topology and flux dynamics with uninterrupted long-duration sequences with large fields of view, allowing a statistical study of flux displacement histories. The program will provide a means for systematic and coherent analysis, specifically focusing on magnetoconvection.***
