In this paper it is argued that recently observed x-ray emission from non-magnetic planets (Dennerl et al., 2002) can be explained as a combination of bremsstrahlung and line K-shell radiation produced by the interaction of energetic electrons wit

Backward wave cyclotron-maser emission in the auroral magnetosphere

Autor: Robert Bingham, David Speirs, B. J. Kellett, Kevin Ronald, Alan D. R. Phelps, I. Vorgul, R. A. Cairns

This work was supported by EPSRC Grant No. EP/G04239X/1. In this Letter, we present theory and particle-in-cell simulations describing cyclotron radio emission from Earth's auroral region and similar phenomena in other astrophysical environments. In

Efficient (similar to 1%) electron cyclotron radio emissions are known to originate in the X mode from regions of locally depleted plasma in the Earths polar magnetosphere. These emissions are commonly referred to as the Auroral Kilometric Radiation
