The magnetosphere as a sufficient source for upstream ions on November 1, 1984

DG Sibeck, RW McEntire, SM Krimigis… - Journal of …, 1988 - Wiley Online Library

Shock drift acceleration of energetic (E ≥ 50 keV) protons and (E ≥ 37 keV/n) alpha particles at the Earth's bow shock as a source of the magnetosheath energetic …

GC Anagnostopoulos… - Journal of Geophysical …, 1994 - Wiley Online Library
We present simultaneous energetic proton (E≥ 50 keV), alpha particle (E≥ 37 keV/n) and
electron (E≥ 220 keV) observations obtained by the spacecraft IMP 8 and IMP 7 for an …

Shock drift acceleration of energetic protons at a planetary bow shock

J Giacalone - Journal of Geophysical Research: Space Physics, 1992 - Wiley Online Library
We present the results of numerical orbit integrations of the interaction of suprathermal
