Kappa Distributions: Theory and Applications in Space Plasmas
Pierrard, V.; Lazar, M.
The plasma particle velocity distributions observed in the solar wind generally show enhanced (non-Maxwellian) suprathermal tails, decreasing as a power law of the velocity and well described by the family of Kappa distribution functions. The presence of non-thermal populations at different altitudes in space plasmas suggests a universal mechanism…
From the Sun to the Earth: The 13 May 2005 Coronal Mass Ejection
Jensen, E. A.; Owens, M. J.; Owen, C. J. +25 more
We report the results of a multi-instrument, multi-technique, coordinated study of the solar eruptive event of 13 May 2005. We discuss the resultant Earth-directed (halo) coronal mass ejection (CME), and the effects on the terrestrial space environment and upper Earth atmosphere. The interplanetary CME (ICME) impacted the Earth's magnetosphere and…
