Multi-spacecraft observations of interplanetary shocks: Non-planarity and energetic particles

M. Neugebauer, J. Giacaione

Research output: Contribution to journalConference articlepeer-review


Numerical simulations of the evolution of interplanetary shocks exhibit growth of distortions of the shock front and non-uniformity of energetic particles from place to place on the shock surface. In this work we use multi-spacecraft (ACE, Wind, IMP 8, Geotail, SOHO, and Genesis) observations near Earth to search for such effects. On scales of 105 to 106 km, most of the shocks studied are inconsistent with planar structures or with spherical structures with a radius of 1 AU. There are also differences in the energetic particle fluxes seen at ACE and Wind.
