Lower hybrid waves at the shock front: a reassessment

Modulational instability of lower hybrid waves at the magnetopause

The role of lower hybrid waves at the magnetopause is reexamined. It is found that for the maximum observed wave power, the lower hybrid waves are unstable to a modulational instability on the magnetosheath side of the magnetopause. The modulational instability leads to localized field structures , oriented predominantly along the magnetic field. Such patchy lower hybrid turbulence has been obs...

A Front Tracking Method for Transitional Shock Waves

Non{strictly-hyperbolic and mixed-type conservation laws pose a challenge to computational methods. Speciically, the computation of transitional shock waves, which are dependent on the parabolic regularization of the conservation laws, is sensitive to the numerical viscosity. In this paper, we propose a front tracking algorithm that treats transitional shock waves correctly. The algorithm inclu...

Lower-hybrid waves in a plasma with negative ions

The introduction of an electronegative gas (i.e., a gas with a large electron attachment cross section, e.g., SF6) into a plasma has made it possible to study plasmas in which the negative ion density can be much larger than the electron density. lp2 In such a plasma, new phenomena may be expected to occur, in particular, various electrostatic wave modes are modified by the presence of negative...
