SHINE Postdoc: Modeling Elevated Charge States in Hot ICMEs and SEP Events to Study Their Inner Coronal Sources

SHINE 博士后:模拟热 ICME 和 SEP 事件中的高电荷态以研究其内日冕源

基本信息

项目摘要

The PI plans to model charge state evolution in the corona and compare the results with in-situ charge state observations from the Advanced Composition Explorer (ACE). She seeks to reconcile observations with models, building on methods and techniques developed by Laming (2004) at NRL, to enable the determination of thermal conditions on the Sun and acceleration mechanisms that produce the charge states observed in ICMEs (interplanetary manifestation of coronal mass ejections) and SEP (solar energetic particle) events. Her main objectives include the measurement and modeling of the charge states of various solar wind ions observed in hot ICMEs and SEPs in order to understand their origin and evolution, as well as to determine whether they arise from common sources on the Sun and how different expansion mechanisms affect their in-situ charge states. The PI asserts that the ionic composition of ICMEs and SEPs is a unique measure of the thermal environment of their coronal source regions. Charge states in the solar wind reflect the electron temperatures in the inner corona while SEPs additionally reflect the acceleration mechanisms that propel them out of the corona. This work will build upon previous efforts that have shown that ionic charge states of heliospheric plasmas are crucial in identifying ICMEs and analyzing the sources of energetic particles accelerated in the heliosphere. This proposed work will be the first ever attempt to model the ionic composition of hot ICMEs and SEP events. The results of this research will enable the modeling communities to validate models of the eruption of CMEs and the acceleration of solar energetic particles from the solar surface and in the heliosphere. Such improved models will assist space weather forecasting. All participants in the PI's planned collaborations have been actively involved in SHINE workshops and research activities.
PI计划模拟日冕中的电荷状态演变,并将结果与高级成分探测器(ACE)的原位电荷状态观测结果进行比较。她试图将观测结果与模型相协调,建立在Laming(2004)在NRL开发的方法和技术的基础上,以确定太阳的热条件和加速机制,这些机制产生了在ICMEs(日冕物质抛射的行星际表现)和SEP(太阳高能粒子)事件中观察到的电荷状态。她的主要目标包括测量和模拟在高温ICMEs和sep中观测到的各种太阳风离子的电荷状态,以了解它们的起源和演化,以及确定它们是否来自太阳上的共同来源以及不同的膨胀机制如何影响它们的原位电荷状态。PI断言,ICMEs和sep的离子组成是其日冕源区域热环境的独特测量。太阳风中的电荷状态反映了内日冕中的电子温度,而sep还反映了将它们推出日冕的加速机制。这项工作将建立在先前的工作基础上,这些工作表明,日球等离子体的离子电荷状态对于识别ICMEs和分析日球层中加速的高能粒子的来源至关重要。这项提议的工作将是首次尝试模拟热ICMEs和SEP事件的离子组成。这项研究的结果将使建模界能够验证cme爆发和太阳高能粒子从太阳表面和日球层加速的模型。这种改进的模型将有助于空间天气预报。PI计划合作的所有参与者都积极参与SHINE讲习班和研究活动。
