Correlated Elemental and Isotopic Variations in Solar Energetic Particles

Abstract
We consider whether the observed fractionation of Ne isotopes recently reported in solar energetic particle (SEP) events is due to the same charge-to-mass dependent fractionation processes that apparently cause SEP elemental composition variations. We find that the observed correlation of the 22Ne/20Ne and Na/Mg ratios in nine large SEP events is consistent with a common fractionation process if the charge states of these ions are characteristic of a source temperature of -1.5 to -4 million degrees.
