Collaborative Research: SHINE: Observational and Theoretical Investigation of Solar Flare Ribbon Elongation

这项为期3年的合作项目将为太阳耀斑的能量释放提供新的物理见解，这是空间气象研究的重要组成部分，对整个社会具有高度重要性。该项目将探索磁重联扩散和粒子充电的物理过程，这些过程的应用超出了SIRE计划的范围。因此，该项目的预期成果应可用于地球磁层的应用，并有可能用于实验室和聚变实验。项目活动将通过资助两名研究生来促进培训和学习。这位首席PI将继续通过密歇根州立大学由NSF赞助的REU项目来指导本科生的研究。到目前为止，领队PI已经指导了13名REU学生，其中6名是女学生。作为该项目的一部分，这位非领导派将继续与西弗吉尼亚州儿童发现博物馆建立富有成效的合作伙伴关系。这个项目的研究和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。这个合作的SIRE项目将探索一种新的和独立的技术来估计太阳日冕高处重联地点的磁场。太阳大气层的这一区域目前无法直接观测到，因此阳光社区对此非常感兴趣。该项目团队将从观测和数值上确定引导磁场强度和粒子加速之间是否存在相关性；两者之间的联系将提供一种新的方法，通过观测太阳耀斑带扩散来估计粒子加速。磁场重联扩散问题是太阳活动界广泛关注的一系列应用，包括日冕喷发，以及在湍急的太阳风中极大地扩展重联区域。

This 3-year collaborative SHINE project will provide new physical insights into the energy release in solar flares, which is an important component of space weather research and is of high importance to society at large. The project will explore the physical processes of magnetic reconnection spreading and particle energization, which have applications beyond the SHINE program. Thus, the expected outcome of this project should be of use for applications in the Earth's magnetosphere, and potentially laboratory and fusion experiments. The project activities will promote training and learning through the funding of two graduate students. The lead PI will continue to supervise undergraduate students' research through an NSF-sponsored REU program at the MSU. Thus far, the lead PI has supervised 13 REU students, with six of them being female students. The non-lead PI will continue his productive partnership with the Children's Discovery Museum of West Virginia as part of this project. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.This collaborative SHINE project will explore a novel and independent technique to estimate magnetic fields at reconnection sites high in the solar corona. This region of the solar atmosphere is currently inaccessible to direct observations, and therefore of great interest to the SHINE community. The project team will determine observationally and numerically whether there is a correlation between the guide magnetic field strength and particle acceleration; a link between the two would provide a novel way to estimate particle acceleration from observations of solar-flare ribbon spreading. The problem of magnetic reconnection spreading is of broad interest to the SHINE community for a number of applications, including prominence eruptions, and greatly expanding the region of reconnection in the turbulent solar wind.
