A Study of the Origins of Solar Active Region Heating

本研究探讨了太阳色球加热与光球层动力学的关系。现有的数据主要集中在NOAA活动区域8844，以及来自各种卫星(Yohkoh，SOHO和TRACE)的特征观测，以及独特的气球实验(耀斑起源实验)。分析不仅要确定光球层的磁场和速度场，还要确定上面过渡区的电子温度和发射测量。将特别强调理解像埃勒曼炸弹这样的小规模瞬变现象。在项目的最后阶段，这些事件将由结合了太阳大气自组织临界行为的元胞自动机模型以及确定性流体力学和磁流体动力学计算来模拟。

This study investigates the mechanisms of solar chromospheric heating in relation to photospheric dynamics. The data available focus on NOAA Active Region 8844, and feature observations from various satellites (Yohkoh, SoHO, and TRACE) as well as a unique balloon-borne experiment (Flare Genesis Experiment). Analysis should determine not only the photospheric magnetic and velocity fields, but also the electron temperature and emission measure in the overlying transition region. Particular emphasis will be placed on understanding small-scale transient phenomena like Ellerman bombs. At the final stage of the project, these events will be modeled by cellular automata models incorporating the self-organized critical behavior of the solar atmosphere, as well as by deterministic hydrodynamic and magneto-hydrodynamic calculations.
