This 3-year project is aimed at advancing present understanding of the origin of solar flares by taking unprecedented high-resolution observations from the newly commissioned 1.6m New Solar Telescope (NST) at the Big Bear Solar Observatory (BBSO) and numerical simulations using radiative hydrodynamic codes. The new observations by the NST are expected to extend the frontier of existing knowledge on the energy release process of flares and its impact on the deep solar atmosphere in terms of both positive and negative contrasts. The observational results will also be compared with numerical simulations in order to have a more complete physical understanding of the observed phenomena. NSF has made significant investment in supporting the BBSO's facilities in the past, in particular the NST, which has been transited from commissioning phase to operations, thus enabling routine high-quality observations of the Sun.This comparative investigation in solar flare phenomena will enable a quantitative analysis of the energy release processes that occur not only on the Sun, but also elsewhere in the solar system and stars. Solar flares are one of the key sources of space weather, which causes adverse impacts on the Earth and its environment. Advanced understanding of the solar flare phenomenon helps improve forecasts of space weather events at their onset.This research project has a strong educational component; it will support a female Ph.D. student and a junior researcher at the NJIT. The studies will provide a comprehensive training for the student in taking observations at the BBSO, data processing and understanding the principals of flare heating models. Therefore, the project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.

这个为期三年的项目旨在通过在大熊太阳天文台（BBSO）新投入使用的1.6米新太阳望远镜（NST）进行前所未有的高分辨率观测和使用辐射流体动力学代码的数值模拟，提高对太阳耀斑起源的了解。预计NST的新观测将在耀斑能量释放过程及其对太阳深层大气影响的正、负对比方面拓展现有知识的前沿。观测结果也将与数值模拟进行比较，以便对观测到的现象有更完整的物理理解。过去，NSF在支持BBSO的设施方面投入了大量资金，特别是NST，它已经从调试阶段过渡到运行阶段，从而能够对太阳进行常规的高质量观测。这种对太阳耀斑现象的比较研究将使我们能够定量分析不仅发生在太阳上的能量释放过程，也发生在太阳系和恒星的其他地方。太阳耀斑是空间天气的主要来源之一，对地球及其环境造成不利影响。对太阳耀斑现象的深入了解有助于提高对空间天气事件的预报。这个研究项目有很强的教育成分；它将资助一名女博士生和一名初级研究员。这些研究将为学生提供全面的训练，使他们能够在天文台进行观测、数据处理和了解耀斑加热模型的原理。因此，该项目支持AGS部门在发现、学习、多样性和跨学科研究方面的战略目标。
