Measuring the Mass Flux and Magnetic Evolution of Jets in the Solar Atmosphere

提出建议的小组将对冕洞喷流的结构和演变进行全面研究，以发现太阳风与太阳表面磁结构之间的联系。该团队将使用Hinode航天器上仪器的数据来测量与导致太阳爆炸事件（EE）和日冕洞射流（CHJ）的磁演化相关的参数，以及测量从这些事件中喷出的质量。爆炸事件和日冕洞喷流特别适合于该小组将进行的光谱分析和磁场研究。该团队特别打算研究太阳的磁场演变如何触发EE和CHJ，以确定EE在太阳色球层和/或日冕中促进可测量响应的频率，并计算CHJ的总质量通量。这项研究将增加我们对低层太阳大气中物质和能量的可变流动的理解。该团队收集的CHJ的综合统计数据将深入了解这些射流在进入日冕和太阳风的质量和能量通量中的可能作用，从而有助于开发改进的预测空间天气模型，该模型依赖于将低太阳大气耦合到日冕。该团队将向公众提供所有分析过的CHJ事件的数据库，以便这项调查的科学结果可以被一般的太阳物理学界进一步利用。这项工作的共同研究者是一位受雇于工业界的女科学家，因此该项目将促进代表性不足的群体参与科学，同时加强正在进行的学术-联邦实验室-工业伙伴关系。

The proposing team will carry out a comprehensive study of the structure and evolution of coronal hole jets in order to discover the connections between the solar wind and magnetic structures at the solar surface. The team will use data from instruments on board the Hinode spacecraft to measure the parameters relevant to the magnetic evolution that leads to explosive events (EEs) and coronal hole jets (CHJs) on the Sun, as well as to measure the mass that is ejected from such events. Explosive events and coronal hole jets are particularly well suited to the spectroscopic analysis and magnetic field studies that this team will perform. The team specifically intends to study how the Sun's magnetic field evolution triggers EEs and CHJs, to determine how often EEs promote a measurable response in the solar chromosphere and/or corona, and to calculate the total mass flux of CHJs. This research will increase our understanding of the variable flow of mass and energy through the lower solar atmosphere. The comprehensive statistics for CHJs collected by this team will provide insight into the possible role of these jets in the mass and energy flux going into the corona and solar wind, and thus aid in the development of improved predictive space weather models that depend on coupling the lower solar atmosphere to the corona. The team will provide a database of all analyzed CHJ events to the public, so that the scientific results of this investigation can be further exploited by the general solar physics community. The co-investigator of this effort is a female scientist employed in industry, so this project will advance the participation of underrepresented groups in science while enhancing an ongoing academic-federal lab-industrial partnership.
