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3年的项目旨在通过从大熊太阳天文台（BBSO）新启用的1.6米新太阳望远镜（NST）进行前所未有的高分辨率观测，并使用辐射流体动力学代码进行数值模拟，来推进目前对太阳耀斑起源的理解。 NST的新观测预计将扩大耀斑能量释放过程及其在正负对比方面对太阳深层大气影响的现有知识的前沿。 观测结果还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。 美国国家科学基金会在过去为支持BBSO的设施进行了大量投资，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。这种太阳耀斑现象的比较研究将能够对不仅发生在太阳上的能量释放过程进行定量分析，而且还可以对太阳系和恒星的其他地方进行定量分析。 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改进空间天气事件发生时的预报。学生和NJIT的初级研究员。 这些研究将为学生提供在BBSO进行观测、数据处理和理解耀斑加热模型原理的全面培训。 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。
