9311834 Schmelz The physical properties of the highly ionized plasma of the solar corona will be investigated using soft X-ray spectral line data previously acquired by the Solar Maximum Mission satellite. The soft X-ray lines provides the redundancy to untangle various observational and theoretical effects, and to test current ideas about the properties of the coronal component of solar active regions. Current analysis methods assume that the observed plasma is optically thin, that the elemental abundance values are constant, than the theoretical behavior of the emissions lines is a well known function of temperature, and that the plasma is isothermal. The analysis methods developed for this investigation do not require these restrictions. Several undergraduate students will be involved in the projects to assist with the data analysis and present the results. ***

小行星9311834 将利用太阳峰年使命卫星先前获得的软X射线谱线数据对日冕高度电离等离子体的物理特性进行研究。 软X射线线提供了冗余来解开各种观测和理论效应，并测试当前关于太阳活动区日冕分量属性的想法。 目前的分析方法假设所观察到的等离子体是光学薄的，元素丰度值是恒定的，而发射线的理论行为是众所周知的温度函数，并且等离子体是等温的。 本研究开发的分析方法不需要这些限制。 一些本科生将参与项目，以协助数据分析和提出的结果。 ***
