Coronal Streamer Belt Morphology

从环绕太阳的一条带延伸出来的一条流光带构成了日冕最密集的部分。最近的研究表明，与地球附近流光带数据的叠加纪元分析相反，该带可能是日冕物质抛射(CME)的来源，而日冕物质抛射是导致地磁暴的原因。数据显示出高度的可变性，与它在日光层的活动一致，但很少有研究关注它的复杂性。该项目的目标是：(1)建立流光带的形态模型；(2)建立地磁暴的预报方案。研究人员将从组合场和等离子体参数流线常数中提取信息，并对它们进行分析，以区分动态星际效应和太阳起源的效应。产生的流光带形态数据将作为未来日光层全球环流模型的任何定量流光带模块的基础。*

A belt of streamers extending from a band encircling the sun comprise the densest portion of the solar corona. Recent research indicates, contrary to superposed epoch analysis of streamer belt data near Earth, this belt may be the source of coronal mass ejections (CMEs), which are responsible for geomagnetic storms. Data shows high variability, consistent with its activity in the heliosphere, yet few studies have focused on its complexities. This project's aim, at both basic and applied levels, is to (1) construct a morphological model of the streamer belt, and (2) establish a prediction scheme for geomagnetic storms. The investigator will draw from combined field and plasma parameter streamline constants, and analyze them to separate dynamic interplanetary effects from those of solar origin. The resulting streamer belt morphology data will serve as a basis for any future quantitative streamer belt module of a global circulation model of the heliosphere.***
