Helium Abundance Variations in Interplanetary Coronal Mass Ejections
Based on the OMNI2 database for the period from 1976 to 2019, the behavior of the relative abundance of helium ions N α / N p is investigated inside interplanetary coronal mass ejections (ICMEs). It is shown that the previously discovered anticorrelation between N α / N p and the parameter β inside...
