Fig. 5: Phase-bunching stripe gaps reproduced in numerical simulations.
From: Particle-sounding of the spatial structure of kinetic Alfvén waves
a The modeled (black) and observed (red) electric fields of the KAWs. b–d The ratio between the final and initial proton energy, which is a proxy for the evolution of proton phase space densities. The orange solid and dashed lines give the expected positions of phase-bunching stripes. Phase-bunching stripes (marked by the orange lines and the bar below panel a) and phase-bunching stripe gaps in agreement with the observations are reproduced.
