A Study of the Origins of Solar Active Region Heating

本研究从光球动力学的角度探讨了太阳色球加热的机理。可用的数据集中在NOAA活动区8844，以及来自不同卫星（Yohkoh， SoHO和TRACE）的观测数据，以及一个独特的气球载实验（耀斑成因实验）。分析不仅要确定光球磁场和速度场，还要确定上覆过渡区的电子温度和发射量。特别强调的是理解像埃勒曼炸弹这样的小尺度瞬变现象。在项目的最后阶段，这些事件将通过包含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动力学和磁流体动力学计算来建模。

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.
