Long-Lived Recurrent Fluxes of Energetic Ions from Coronal Holes on the Sun

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Results are presented from studying the relative abundances and energy spectra of 4He, C, O, and Fe suprathermal ions in particle fluxes from long-lived near-equatorial coronal holes. It is found that the ion energy spectra have a power or exponential form. Increased particle fluxes are observed in a number of events in the region of low ion energies (~0.2–1.5 MeV/nucleon), creating fractures in the spectra that could be due to additional ions accelerated beyond 1 au.
