This 3-year SHINE project is aimed at gaining a comprehensive understanding of the physical connection between small-scale physical processes at magnetic reconnection sites in the solar atmosphere and the evolution of solar eruptions at greater scales. This, the project has the potential to significantly advance knowledge of the energy release process in solar eruptions. In particular, the project will explore the relationship between small-scale energy release in the form of outflows in the current sheet region and the large-scale transport of thermal energy in the flare structure. The integrated modeling efforts will form the basis of the development of a more sophisticated, full three-dimensional (3-D) simulation of solar eruptions in the future.The 3-year research program integrates two sets of well-developed, state-of-the-art magnetohydrodynamics (MHD) simulations: one simulation models the large-scale structure and evolution of solar flares, whereas the other simulation targets detailed dynamics in and around the reconnection current sheet region at small scales. The large-scale flare simulation will be used to set up the context and initial conditions for the detailed full 3-D simulation of the reconnection region. The outputs of the detailed small scale 3-D simulation, in turn, will provide feedback and update the large-scale simulation to evaluate the consequences of small-scale energy release processes. The modeling results will be compared with extreme ultraviolet (EUV) and X-ray observations to test and improve our understanding of the energy release and conversion processes from small to large scales. A variety of well observed, but poorly understood phenomena that are closely tied to the energy release processes will be investigated and compared to model outputs, including supra-arcade down-flows and other fast plasma outflows, current-sheet like structures above flare loops, and hot loop-top EUV/X-ray sources.The improved knowledge on the origin of solar eruptions is critical to understand basic science needed to meet the goals of the National Space Weather Strategy and Action Plan, which aims to develop tools to forecast space weather and mitigate its impacts. The project team will involve students in this SHINE research through the established CfA's Solar Physics Research Experiences for Undergraduates (REU) program. These students come from a wide variety of backgrounds, including traditionally underrepresented groups in the sciences. Thus, the research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.

这个为期三年的光泽项目旨在全面了解太阳大气中的磁重新连接位点的小规模物理过程与更大尺度上太阳喷发的演变。 这是该项目有可能显着提高太阳喷发中能量释放过程的知识。 特别是，该项目将以流出区域的流出形式与火炬结构中热能大规模运输的形式探索小规模能量释放之间的关系。 The integrated modeling efforts will form the basis of the development of a more sophisticated, full three-dimensional (3-D) simulation of solar eruptions in the future.The 3-year research program integrates two sets of well-developed, state-of-the-art magnetohydrodynamics (MHD) simulations: one simulation models the large-scale structure and evolution of solar flares, whereas the other simulation targets detailed dynamics in and around the重新连接电流区域的小尺度。 大规模耀斑模拟将用于设置重新连接区域详细完整3-D模拟的上下文和初始条件。 详细的小型3-D模拟的输出又将提供反馈并更新大规模模拟，以评估小规模能量释放过程的后果。 模型结果将与极端紫外线（EUV）和X射线观测值进行比较，以测试和提高我们对从小到大尺度的能量释放和转换过程的理解。 将研究与能量释放过程紧密相关的现象，并将其与模型的产出相关的各种现象，并将其与模型输出进行比较行动计划旨在开发工具以预测太空天气并减轻其影响。 该项目团队将通过既定的CFA本科生（REU）计划的CFA太阳能物理研究经验参与这项Shine研究。 这些学生来自各种各样的背景，包括传统的科学中代表性不足的群体。 因此，该项目的研究和EPO议程支持AGS部门在发现，学习，多样性和跨学科研究方面的战略目标。
