TL;DR: A revised version of the selfconsistent theory of ion diffusive shock acceleration and the associated generation of hydromagnetic waves is presented in this paper, where the wave growth or damping rate is again calculated using linear theory, but a more general ion anisotropy is calculated using the pitch angle diffusion equation.

TL;DR: In this paper, a statistical study of diffuse energetic ion events and their related waves upstream of the Earth's bow shock was performed using data from the Active Magnetospheric Particle Tracer Explorers/Ion Release Module (AMPTE/IRM) satellite over two 5-month periods in 1984 and 1985.

TL;DR: In this paper, the authors used multispacecraft studies using Polar, Fast Auroral Snapshot (FAST), and Interball observations to show that many cusp structures observed during stable solar wind conditions are spatial features.

TL;DR: In this article, the authors show that large-scale cusp structures for this Cluster cusp crossing are in agreement with structures in the convection pattern and conclude that major cusp structure can be consistent with a spatial phenomenon.

TL;DR: In this paper, a statistical analysis of the correlation of solar wind parameters with variation of the ion energy spectra by making use of energetic ion measurements with the time-of-flight spectrometer SULEICA on AMPTE/IRM was performed.
