中文摘要
首席研究员(PI)将开发一个日冕物质抛射(CME)和太阳耀斑排放的综合模型,以充分说明此类爆发事件期间释放的能量。这将使人们有可能将观测到的低日冕发射特性与所产生的日冕物质抛射的速度和加速度联系起来。该项目将通过使用SAIC开发的复杂数值CME模型来改进PI以前的工作,以获得对CME能量释放,重连物理和动力学的新见解。模拟事件的耀斑发射也将被模拟,从而探索CME和耀斑之间的联系。该项目将阐明太阳爆发现象背后的基本物理学。PI将在波士顿科学博物馆创建一个互动的,动手的太阳物理学展览,她目前正在为华盛顿国家航空航天博物馆的太阳天文学展览开发内容。在该项目期间,PI还将在三名年轻女科学家的职业生涯开始时担任他们的导师。这项研究工作将通过开发诊断工具来帮助预测可能损坏卫星、电网和石油管道以及破坏电信和导航的空间天气条件,从而造福社会。
英文摘要
The Principal Investigator (PI) will develop an integrated model of coronal mass ejections (CMEs) and solar flare emissions that fully accounts for the energy released during such eruptive events. This will make it possible to relate the observed properties of emissions in the lower corona to the velocity and acceleration of resulting CMEs. This project will improve upon the PI's previous work by using a sophisticated numerical CME model developed by SAIC to gain new insights into CME energy release, reconnection physics, and dynamics. Flare emission from simulated events will also be modeled, allowing connections between CMEs and flares to be explored. This project will elucidate the fundamental physics underlying eruptive phenomena on the Sun.The PI will create an interactive, hands-on solar physics exhibit at the Boston Museum of Science, and she is currently developing content for an exhibit on solar astronomy at the National Air and Space Museum in Washington DC. During this project, the PI will also serve as a mentor to three young women scientists at the beginning of their careers. This research effort will benefit society by developing diagnostic tools to aid in forecasting the space weather conditions that can damage satellites, power grids, and oil pipelines, as well as disrupt telecommunications and navigation.
