SHINE: Reconstructing Interplanetary Coronal Mass Ejection Evolution Using In-Situ Filament Plasma

这个为期3年的SIRE项目的主要目标是通过研究行星际日冕物质抛射(ICME)演化的物理，特别是与日冕物质抛射的丝状物质及其对抛射物能量的反映有关的物理，来改善目前对日冕物质抛射(CME)加热和加速的理解。现场数据和新的分析技术都将首次用于测量重离子的低电荷态，揭示了以前未被探测到的ICME核心材料。这个项目的科学目标与SINE社区的核心主题高度相关。研究工作的一个基本部分是将密歇根大学安娜堡分校年轻科学家的专业知识与经验丰富的研究人员的专业培训相结合。这项工作除了向该社区提供一份关于冰冷冰盖机制的现场观测的全面清单外，还将提供所涉及的等离子体的热历史。社区未来的模型将受到这些等离子结果的约束和改进。通过将本科生水平的研究人员包括在几项数据分析任务中，这项工作也将成为一种工具，为正在崛起的一代提供教育和经验。该项目的研究和欧洲空间局的议程支持AGS司在发现、学习、多样性和跨学科研究方面的战略目标。这一SISH项目产生的全面调查将通过两个主要目标将日光层中的ICME冷物质与太阳喷发过程联系起来：(1)确定冰丝物质在ICME内的普遍存在；(2)确定CME等离子体在喷发过程中的物理性质，这些物理性质负责在从日冕进入日光层的途中保存或消除暗条物质。密歇根电离程序(MIC)将被用来预测暗条中的电荷态演化，以：(I)研究喷发过程中高电荷态的形成和低电荷态离子的存活；以及(Ii)重建喷发暗条的能量学，包括从发射到凝固点的等离子体的温度、密度和速度演化。因此，该项目的成果预计将对太阳-日球界产生重大价值，尤其是大放异彩。

The main goal of this 3-year SHINE project is to improve present understanding of the heating and acceleration of Coronal Mass Ejections (CMEs) by examining the physics of interplanetary CME (ICME) evolution, especially as it relates to the filament material and its reflection of the energization of the ejecta. In-situ data and new analysis techniques will both be employed to measure the low charge states of heavy ions for the first time, revealing previously undetected ICME core material. The science objectives aimed with this project are highly relevant to topics that are central to the SHINE community. A fundamental part of the research work integrates the expertise of young scientists at the University of Michigan at Ann Arbor with the professional training of seasoned researchers. In addition to providing the community with a comprehensive list of in-situ observations of cold ICMEs, this work will also provide a thermal history of the plasma involved. Future models by the community will be constrained and improved by these plasma results. By including researchers at the undergraduate level in several of the data analysis tasks, this work will also act as a tool to educate and give experience to the rising generation. The research and EPO agenda of this project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.The comprehensive survey to result from this SHINE project will relate cold ICME material in the heliosphere to the eruption process at the Sun through two main objectives: (i) determine the prevalence of filament material within ICMEs; and, (ii) determine the physical properties of the CME plasma during the eruption process that are responsible for either preserving or obliterating filament material on its way from the corona into the Heliosphere. The Michigan Ionization Code (MIC) will be used to predict charge state evolution in the filament in order to: (i) investigate the formation of higher charge states and the survival of low charge state ions during the eruption process; and, (ii) reconstruct the energetics of erupting filaments, including the temperature, density, and velocity evolution of the plasma from launch to the freeze-in point. Thus, the outcome of this project is expected to be of great value to the solar-heliospheric community, and SHINE in particular.
