Measurements from ground-based magnetometers and riometers at auroral latitudes have demonstrated that energetic (similar to 30-300 keV) electron precipitation can be modulated in the presence of magnetic field oscillations at ultralow frequencies. It has previously been proposed that an...

We consider electron acceleration by kinetic Alfvén waves in the equatorial inner magnetosphere and plasma sheet boundary layer. The competition between the accelerating effect of the wave parallel electric field and mirror force acting on particles in an inhomogeneous background magnetic field...

Pitch angle scattering of electrons can limit the stably trapped particle flux in the magnetosphere and precipitate energetic electrons into the ionosphere. Whistler mode waves generated by a temperature anisotropy can mediate this pitch angle scattering over a wide range of radial distances and...
