TL;DR: In this article, the relationship between the solar wind and magnetospheric ULF waves was investigated using the Lyon-Fedder-Mobarry global, three-dimensional magnetohydrodynamic (MHD) code.

TL;DR: In this article, the formation of acoustic double layers in the presence of two ion species is examined. But the results are restricted to the case of a single ion component and do not account for the effect of having two ion components.

Abstract: Electromagnetic ion cyclotron (EMIC) waves are mostly left-hand-polarized waves observed in the 0.1–5 Hz range in the inner magnetosphere. These waves are generated near the equator by the temperature anisotropy of ring current ions either injected from the plasma sheet during geomagnetic storms or substorms or transversely heated by dayside magnetopause compression (Anderson et al., 1992; McCollough et al., 2010; Usanova et al., 2010). In a plasma containing H and He ions, EMIC waves can be generated in two distinctive bands below and above the helium gyrofrequency (Stix, 1962; Summers & Thorne, 2003; Zhang et al., 2016).

TL;DR: In this article, measurements of the inner magnetosphere during solar cycle 23 for the signature of a particular form of the Sun-Earth connection were surveyed for the creation of new ion radiation belts.

TL;DR: In this paper, it was shown that the wave spectral properties are ordered with respect to the proton parallel beta, {beta}{sub {parallel}p} and the later result is predicted by linear Vlasov theory using a simple model for the magnetosheath and plasma depletion layer.
