The Origins and Implications of Solar Flare and CME-Related Magnetic Field Changes

首席调查员(PI)和她的团队将结合建模和数据分析来研究太阳上耀斑相关的磁变化(FAMCs)的原因和后果。该团队将分析日冕物质抛射(CME)的磁流体动力学(MHD)模拟的输出，以调查模拟的日冕中的磁结构如何影响模拟区域基础上的磁场。为了更好地了解日球层的影响，PI和她的团队将调查观测到的日球运动与观测到的日冕物质运动的速度、质量和动量的相关性，以及在模拟中观测到的日球运动和日冕物质抛射性质之间的任何相关性。为了研究FAMC如何有效地驱动“太阳地震”，该团队将使用来自卫星观测及其模拟的不同参数，以初始化对流太阳内部的MHD模型，并表征太阳对真实太阳地震脉冲的声学响应。国际和平研究所预计，对太阳磁暴的这项研究将有助于发展必要的了解和工具，以提高我们对可能对我们以技术为基础的社会产生不利影响的强烈空间天气事件的预测能力。她将通过她的研究所的网站向研究界提供她的团队的新数据集，包括她的观测分析和MHD模拟数据。PPI指出，社区对该项目的数据和建模结果的可访问性将为科学家和学生提供进行空间气象研究的额外工具。与此同时，PI的团队将通过为加州大学伯克利分校的学生提供服务，促进教学、培训和学习，同时促进发现和科学理解。PI的团队拥有监督学生研究人员的经验，他们计划从伯克利的物理学、天文学和行星科学系吸引和招聘高素质的本科生和研究生，同时加强研究和教育的基础设施。

The Principal Investigator (PI) and her team will study the causes and consequences of flare-associated magnetic changes (FAMCs) on the Sun by using a combination of modeling and data analysis. The team will analyze the output of magnetohydrodynamic (MHD) simulations of coronal mass ejections (CMEs) to investigate how magnetic restructuring in the modeled solar corona affects the magnetic field at the base of the simulation domain. In order to better understand the heliospheric consequences of FAMCs, the PI and her team will investigate correlations of observed FAMCs with the speeds, masses, and momenta of observed CMEs, as well as any correlations of the properties of FAMCs and CMEs in their simulations. To investigate how effectively FAMCs can drive "sunquakes," the team will use different parameterizations derived from satellite observations and their simulations, in order to initialize MHD models of the convecting solar interior and to characterize the Sun's acoustic response to realistic sunquake impulses. The PI expects that this study of solar magnetic eruptions will help develop the necessary understanding and tools to improve our prediction capability for the strong space weather events that can adversely affect our technology-based society. She will deliver her team's new data sets to the research community, including her observational analysis and MHD simulation data, through her institute's web site. The PI notes that community accessibility to this project's data and modeling results will provide scientists and students additional tools to perform space weather research. Meanwhile, the PI's team will promote teaching, training, and learning while advancing discovery and scientific understanding by serving students at the University of California at Berkeley. The PI's team has experience supervising student researchers, and they plan to attract and recruit highly qualified undergraduate and graduate students from the Physics, Astronomy, and Planetary Science Departments at Berkeley, while enhancing infrastructure for research and education.
