Coronal Temperature and Spicular Density Studies at the 1991 Eclipse

这项研究将研究太阳日冕的温度， 太阳色球密度 针状体，通过观察它们的连续光谱， 在日全食的时候 1991年7月11日的太阳。 强度的精确测定 某些光谱线的变化 对日冕电子温度的独立测定 日全食允许一个测量太阳辐射作为一个 日面高度函数 四肢 从这种辐射可以推断出 和密度 色球层 推导出的物理条件将是 有助于改进模型， 小色球结构。

This research will study the temperature of the solar corona and the density of solar chromospheric spicules through observations of their continuous spectra carried out at the total solar eclipse of the Sun on July 11, 1991. Accurate determinations of the intensities of certain spectral lines can lead to an independent determination of coronal electron temperatures. Total solar eclipses allow one to measure the solar emission as a function of altitude above the solar limb. From this emission it is possible to deduce the temperature and the density of the chromosphere. The physical conditions that are deduced will be useful for improving models for small chromospheric structures.
