项目摘要

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.

这个为期 3 年的合作 SHINE 项目将为太阳耀斑能量释放提供新的物理见解，这是空间天气研究的重要组成部分，对整个社会非常重要。该项目将探索磁重联扩散和粒子赋能的物理过程，这些过程的应用超出了 SHINE 项目的范围。因此，该项目的预期成果应可用于地球磁层的应用，以及潜在的实验室和聚变实验。该项目活动将通过资助两名研究生来促进培训和学习。首席 PI 将继续通过 NSF 资助的密歇根州立大学 REU 项目来监督本科生的研究。到目前为止，首席 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，非首席 PI 将继续与西弗吉尼亚州儿童探索博物馆保持富有成效的合作关系。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。该合作 SHINE 项目将探索一种新颖且独立的技术来估计日冕高处重联点的磁场。太阳大气层的这个区域目前无法直接观测，因此 SHINE 社区对此非常感兴趣。项目组将通过观测和数值确定引导磁场强度与粒子加速度之间是否存在相关性；两者之间的联系将提供一种根据太阳耀斑带状扩散的观测来估计粒子加速度的新颖方法。磁重联扩散问题引起了 SHINE 社区的广泛关注，其应用范围包括日珥喷发，以及极大地扩展湍流太阳风中的重联区域。
