Effects of High Ion Temperatures on Spectral Line Diagnostics in the Source Region of the High-speed Solar Wind

摘要

Theoretical work on solar wind acceleration has suggested that the proton and electron temper- atures at the base of the solar coronal hole region are not thermally equilibrated but that instead the proton temperature may exceed the electron temperature significantly. Recently, Kohl, Strachan, & Gardner have measured both broad and narrow components of the H Lyα profile and have suggested that the broad component may be the signature of high proton temperatures, ～46 * 10~6 K or more.
