1. Evidence for chorus-driven electron acceleration to relativistic energies from a survey of geomagnetically disturbed periods

   [1] We perform a survey of the plasma wave and particle data from the CRRES satellite during 26 geomagnetically disturbed periods to investigate the viability of a local stochastic electron […]

2. Evolution of energetic electron pitch angle distributions during storm time electron acceleration to megaelectronvolt energies

   We investigate the pitch angle distributions of 0.15-1.58 MeV electrons observed during the 9-15 October 1990 storm measured by the Combined Release and Radiation Effects Satellite (CRRES) spacecraft. This storm […]

3. Favored regions for chorus-driven electron acceleration to relativistic energies in the Earth’s outer radiation belt

   [1] Pitch angle and energy diffusion rates for scattering by whistler-mode chorus waves are proportional to the wave magnetic field intensity and are strongly dependent on the frequency distribution of […]

4. Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES

   Electromagnetic ion cyclotron (EMIC) waves which propagate at frequencies below the proton gyrofrequency can undergo cyclotron resonant interactions with relativistic electrons in the outer radiation belt and cause pitch-angle scattering […]

10. Plasmasphere dynamics in the duskside bulge region: a new look at an old topic

    Data acquired during several multiday periods in 1982 at ground stations Siple, Halley, and Kerguelen and on satellites DE 1, ISEE 1, and GEOS 2 have been used to investigate […]

11. Survey of upper band chorus and ECH waves: implications for the diffuse aurora

    The origin of the diffuse aurora has been a source of controversy for many years. More recently, the question has taken a new significance in view of the associated changes […]

12. Substorm dependence of chorus amplitudes: Implications for the acceleration of electrons to relativistic energies

    Intense interest currently exists in determining the roles played by various wave-particle interactions in the acceleration of electrons to relativistic energies during/following geomagnetic storms. Here we present a survey of […]
