A statistical study of the properties of interplanetary coronal mass ejections from 0.3 to 5.4 AU

Liu, Y.; Richardson, J. D.; Belcher, J. W.

We make a comprehensive survey of interplanetary coronal mass ejections (ICMEs) observed by the Helios 1 and 2, Ulysses, WIND and ACE spacecraft, which together cover heliocentric distances from 0.3 to 5.4 AU. The signatures used to identify ICMEs are enhanced helium abundances and depressed proton temperatures. We use the ICME list to study the r…
