Solar Wind Particle Distribution Function Fitted via the Generalized Kappa Distribution Function: Cluster Observations

Lundin, R.; Balogh, A.; Dandouras, I. +17 more

One of the major issues in space plasma physics is that in spite of the inhomogeneity of interplanetary plasma and the complicated magnetic field topology we do not find strong deviations from Maxwellian distributions as it would be expected for a quasi-collisionless plasma. However, the presence of high energy tail and shoulders in the profile of…

Solitary Waves Observed By Cluster In the Solar Wind

Fränz, M.; Dandouras, I.; Génot, V. +6 more

Short dropouts of the magnetic field intensity have been frequently observed in the solar wind on interplanetary spacecraft. But so far it could not be established whether these are caused by kinetic instabilities or whether they can be described as solitary MHD waves. The multi-satellite observations of the Cluster-mission allow for the first tim…
