Advancements in Plasma Wave Generation and Wave-Particle Interactions in Space Plasmas

This presentation highlights some advancements in understanding plasma wave generation and wave-particle interactions in space plasmas. Utilizing data from the Van Allen Probes, we conducted a comprehensive analysis of whistler-mode chorus waves, revealing key properties such as source regions, element durations, and the role of magnetic field inhomogeneity. Further comparative studies of plasma waves across different planets provided crucial evidence supporting the universality of the TaRA model. Additionally, we discovered two distinct forms of energy coupling between plasma waves: between whistler-mode waves through wave beating, and between high-frequency electromagnetic ion cyclotron (EMIC) waves and magnetosonic (MS) waves, driven by anisotropic low-energy protons. These findings significantly enhance our understanding of space plasma dynamics and have broad implications for theoretical models and future research in the field.
