论文摘要

高速太阳风通常是在气球中最简单,最不随机类型的大规模等离子体流动。在太阳周期的大部分时间里,它磁通量连接到太阳表面上的大极冠状孔。由于这些特征是相对众所周知的(并且不如慢速的多个来源区域复杂),因此快风通常是冠状加热理论模型的有用测试。为了为这些模型提供全球经验约束,在这里,我们将一些质子,电子和氧气温度的较旧的,更近的测量结果收集到径向距离的函数。

The high-speed solar wind is typically the simplest and least stochastic type of large-scale plasma flow in the heliosphere. For much of the solar cycle, it is connected magnetically to large polar coronal holes on the Sun's surface. Because these features are relatively well-known (and less complex than the multiple source-regions of the slow wind), the fast wind is often a useful testing-ground for theoretical models of coronal heating. In order to provide global empirical constraints to these models, here we collect together some older and more recent measurements of the temperatures of protons, electrons, and oxygen ions as a function of radial distance.
