Wave turbulence in magnetized plasmas
Galtier, S.
The paper reviews the recent progress on wave turbulence for magnetized plasmas (MHD, Hall MHD and electron MHD) in the incompressible and compressible cases. The emphasis is made on homogeneous and anisotropic turbulence which usually provides the best theoretical framework to investigate space and laboratory plasmas. The solar wind and the coron…
Plasma waves above the ion cyclotron frequency in the solar wind: a review on observations
Briand, C.
Since the very beginning of the space venture, discrepancies between hydrodynamic models and observations have raised the attention to the kinetic effects taking place in the interplanetary medium. After discussing some of these constraints, a review on the state of the art knowledge on the waves in the range fci<f<fpe …
Electrostatic solitary waves in current layers: from Cluster observations during a super-substorm to beam experiments at the LAPD
Gurnett, D. A.; Lakhina, G. S.; Tsurutani, B. T. +15 more
Electrostatic Solitary Waves (ESWs) have been observed by several spacecraft in the current layers of Earth's magnetosphere since 1982. ESWs are manifested as isolated pulses (one wave period) in the high time resolution waveform data obtained on these spacecraft. They are thus nonlinear structures generated out of nonlinear instabilities and proc…
Solar wind interaction with the Earth's magnetosphere: the role of reconnection in the presence of a large scale sheared flow
Califano, F.; Pegoraro, F.; Faganello, M. +1 more
The Earth's magnetosphere and solar wind environment is a laboratory of excellence for the study of the physics of collisionless magnetic reconnection. At low latitude magnetopause, magnetic reconnection develops as a secondary instability due to the stretching of magnetic field lines advected by large scale Kelvin-Helmholtz vortices. In particula…
On the ionospheric coupling of auroral electric fields
Marklund, G. T.
The quasi-static coupling of high-altitude potential structures and electric fields to the ionosphere is discussed with particular focus on the downward field-aligned current (FAC) region. Results are presented from a preliminary analysis of a selection of electric field events observed by Cluster above the acceleration region. The degree of coupl…
