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…
