项目摘要
Understanding the details of solar energetic particle (SEP) acceleration is critical for accurate predictions of space weather and potential impacts on sensitive space-based assets. This 3-year SHINE project is aimed at studying SEP events associated with filament eruptions on the Sun. The goal is to isolate and investigate SEPs accelerated at CME-driven shocks with minimal flare material contributions. The work expands on other researchers' recent results by using more instruments to cover a broader energy range and extend the analysis. The methodology involves spectral and elemental composition data analysis techniques that are well established. The dissemination of the scientific results will be made broadly to the scientific and space weather prediction communities through published articles, scientific talks, and personal communications. In addition, project results and relevant data sets will be made available via the public web pages of the ACE and STEREO Science Centers. The three project teams have excellent track record of publications, participating (often in leadership roles) in various workshops (e.g., SHINE), and attending scientific conferences. Both the team leader and a Co-PIs are under-represented minorities and funding is included for the involvement of an undergraduate student. The project will promote strong international collaborations for the benefit of advancing space weather research both in the USA and worldwide. The research plan of this 3-year SHINE project includes four main tasks. The first task is to examine the characteristics of heavy ions for previously identified events. The spectral shape variation as a function of particle species reveals characteristics of the accelerating shock, while the composition provides important clues regarding the SEP seed population. The second task is to study smaller SEP events associated with filament eruptions by using the more sensitive SEP sensors onboard ACE and STEREO. The inclusion of STEREO data alone has the potential to increase the number of events suitable for study and, in combination with near-Earth spacecraft, allows the examination of SEP characteristics as a function of longitude. The third task is to define stronger constrains on the primary acceleration region by combining calculations of the particle-release times, for both for single-and multiple-spacecraft events, with timing of the corresponding solar signatures. The fourth task is to study in detail similar filament eruption events without associated SEP events in order to identify specific features that are key to SEP generation. The project is directly relevant to the NSF's SHINE program, because it will provide important knowledge about the acceleration and transport of SEPs during solar eruptive events. Such knowledge is critical for accurate modeling and prediction of space weather conditions from the solar surface to the Earth and beyond. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.
了解太阳高能粒子(SEP)加速的细节对于准确预测空间天气和对敏感天基资产的潜在影响至关重要。 这个为期3年的SHINE项目旨在研究与太阳上的灯丝爆发有关的SEP事件。 我们的目标是隔离和调查SEP加速CME驱动的冲击与最小的耀斑材料的贡献。 这项工作通过使用更多仪器来覆盖更广泛的能量范围并扩展分析,扩展了其他研究人员最近的结果。 该方法包括光谱和元素组成数据分析技术,是完善的。 将通过发表文章、科学讲座和个人通信,向科学界和空间天气预测界广泛传播科学成果。 此外,将通过ACE和STEREO科学中心的公共网页提供项目结果和相关数据集。 这三个项目小组在出版物方面有着出色的记录,参加了各种讲习班(例如,#21453;,并参加科学会议。 团队负责人和一个共同的PI都是代表性不足的少数民族,资金包括一名本科生的参与。 该项目将促进强有力的国际合作,以推进美国和全世界的空间气象研究。 SHINE项目的研究计划包括四个主要任务。 第一个任务是检查以前确定的事件的重离子的特性。 作为粒子种类的函数的光谱形状变化揭示了加速冲击的特征,而组成则提供了有关SEP种子种群的重要线索。 第二个任务是通过使用ACE和STEREO上更灵敏的SEP传感器来研究与暗条爆发相关的较小SEP事件。 仅列入立体声观测数据就有可能增加适合研究的事件数量,并与近地航天器相结合,可以检查SEP随经度变化的特性。 第三项任务是通过结合计算粒子释放时间(对于单航天器和多航天器事件)和相应的太阳特征的时间,确定对主加速区域的更强约束。 第四个任务是详细研究类似的灯丝喷发事件,没有相关的SEP事件,以确定特定的功能,是SEP生成的关键。 该项目与NSF的SHINE计划直接相关,因为它将提供有关太阳爆发事件期间SEP加速和运输的重要知识。 这类知识对于准确建模和预测从太阳表面到地球及其以外的空间气象条件至关重要。 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。
