AI模型MAGiDiff从紫外/极紫外滤光图估算太阳磁场

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了MAGiDiff，一种利用去噪扩散模型从紫外/极紫外滤光图估算光球矢量磁场的新型机器学习方法。该方法旨在克服直接测量的挑战，而直接测量通常需要复杂的斯托克斯矢量反演。MAGiDiff以太阳动力学天文台（SDO）/大气成像仪（AIA）的滤光图作为输入，并经过训练以输出可与日出号/太阳光学望远镜-光谱偏振计（Hinode / SOT-SP）相媲美的矢量磁图。该模型在模仿真实数据方面表现出准确性，并显示出跨太阳周期泛化以及适应其他极紫外仪器的能力。 AI

影响 这种由AI驱动的方法可以通过提供更易获得的矢量磁图数据来增强太阳活动建模和预测。
