The Energy Spectra of Suprathermal Tails in Solar Wind Iron
Abstract
High speed suprathermal tails with a fixed energy spectrum have been observed in solar wind H+ and He2+, as well as in He+ pickup ions (e.g. Gloeckler et al., 2007). The presence of the tails have implications for particle injection into the interplanetary shock acceleration process. The suprathermal tails of solar wind Fe have been investigated with the STEREO/PLASTIC mass spectrometer. The energy spectra will be presented for periods of slow and fast solar wind, and for the entire STEREO mission.
