Journal ArticleDOI
Evidence of a Cascade and Dissipation of Solar-Wind Turbulence at the Electron Gyroscale
TL;DR: The first direct determination of the dissipation range of magnetofluid turbulence in the solar wind at the electron scales is reported and a remarkable agreement with theoretical predictions of a quasi-two-dimensional cascade into Kinetic Alfvén Waves (KAW).
Journal ArticleDOI
Universality of Solar-Wind Turbulent Spectrum from MHD to Electron Scales
Olga Alexandrova,Olga Alexandrova,Joachim Saur,C. Lacombe,André Mangeney,John Mitchell,Steve J. Schwartz,Patrick Robert +7 more
TL;DR: It is shown that the electron Larmor radius plays the role of a dissipation scale in space plasma turbulence and the spectra form a quasiuniversal spectrum following the Kolmogorov's law at MHD scales.
Journal ArticleDOI
Plasma sheet instability related to the westward traveling surge
Aurélien Roux,S. Perraut,Patrick Robert,A. Morane,Arne Pedersen,A. Korth,G. Kremser,B. Aparicio,D. Rodgers,R. J. Pellinen +9 more
TL;DR: In this article, a detailed analysis of an isolated dispersionless substorm is performed on the basis of field and particle data collected in situ by the geostationary satellite GEOS 2 and of data from ground-based instruments installed close to the GEOS2 magnetic footprint.
Journal ArticleDOI
Four‐point Cluster application of magnetic field analysis tools: The Curlometer
TL;DR: In this article, the authors focus on the first application of the Curlometer (direct estimation of the electric current density from curl(B), using measured spatial gradients of the magnetic field) analysis technique.
Journal ArticleDOI
A systematic study of ULF Waves Above FH+ from GEOS 1 and 2 Measurements and Their Relationships with proton ring distributions
S. Perraut,Alain Roux,Patrick Robert,Roger Gendrin,Jean-André Sauvaud,Jean-Michel Bosqued,G. Kremser,A. Korth +7 more
TL;DR: In this article, a detailed analysis of the ULF noise observed on the GEOS magnetic antennas in the frequency range ∼0.2'12 Hz has revealed the properties of structured emissions occurring just above the proton gyrofrequency whose existence was reported by Russell et al. (1970) and Gurnett (1976).
