Consequences of oblique chorus waves on the loss and acceleration of trapped electrons

Intense oblique chorus waves have been observed by CLUSTER (and other satellites) off the equator, mainly in the dawn/dayside sector. We examine the effects of these oblique waves on the loss and energization rates of trapped electrons, evaluating them analytically and comparing to results of numerical calculations taking into account realistic wave-normal and intensity distributions of the waves. We show that losses strongly increase due to resonant wave-particle interaction with oblique waves, while energy diffusion rates are not strongly affected. Different physical implications are discussed by comparing our estimates to some observations.
