摘要：

Auroral brightening driven by interplanetary shocks on Earth's closed magnetic field lines is commonly attributed to the 0.1–10keV electron precipitations by electron cyclotron harmonic waves and whistler-mode chorus waves in the low-density region. In contrast, we propose here a new candidate driver, high-frequency whistlers in the high-density plasmasphere. Theoretical calculations predict the comparable abilities of whistler-mode waves with sufficiently high frequencies inside the plasmasphere and chorus waves outside to produce auroral ele...
