Energetic particle cross-field diffusion: Interaction with Magnetic Decreases (MDs)
Lakhina, G. S.; Tsurutani, B. T.; Galvan, C. +3 more
Magnetic field Decreases (MDs) are detected in the heliospheric polar regions. The MDs have minimum spatial scales sizes of 25 proton thermal gyroradii, and are typically bounded by tangential or rotational discontinuities. The distribution of the magnitudes of the decreases within AIDs is a continuum, with the smallest decreases being most freque…
Dissipation and wave-ion interaction in the solar wind: Links between fluid and kinetic theory
Marsch, E.
In this paper we establish links between turbulence dissipation and wave-particle interactions in the solar corona and wind. Based on quasilinear theory, a set of anisotropic, multi-component fluid equations is derived, which describe the wave-particle interactions of ions with Alfvén waves and ion-cyclotron waves or magnetosonic waves propagating…
