Magnetic turbulence in space plasmas: in and around the Earth's magnetosphere
Zimbardo, Gaetano
In collisionless space plasmas most phenomena are governed by wave particle interaction and by the interaction with the large scale fields. Low frequency magnetic turbulence in the solar wind is relatively well characterized and understood. The situation is more complicated for magnetic turbulence in and around the Earth's magnetosphere, where the…
Why is the Sun's corona so hot? Views from SOHO, Yohkoh and solar eclipses
Phillips, Kenneth J. H.
It has been known for over 50 years that the outer atmosphere of the Sun, the so-called corona, has a temperature of 106 K (~0.1 keV) yet the exact reasons for this are still being debated. The magnetic field that pervades the corona is certainly the source of the heating, but the question is whether the field energy is dissipated via n…
Magnetized vortex tubes in the solar wind plasma
Moussas, X.; Polygiannakis, J. M.
We make new applications of our previously proposed method for estimating the strain-rate tensor and vorticity vector in plasmas (concerning the local deformation and self rotation of the plasma fluid elements, respectively) solely from magnetic field time series. Here we use solar wind measurements of Ulysses spacecraft made in the outer heliosph…
Nonlinear electromagnetic waves and spherical arc-polarized waves in space plasmas
Neubauer, Fritz M.; Tsurutani, Bruce T.; Glassmeier, Karl-Heinz +3 more
We review observations of nonlinear plasma waves detected by interplanetary spacecraft. For this paper we will focus primarily on the phase-steepened properties of such waves. Plasma waves at comet Giacobini - Zinner measured by the international cometary explorer (ICE), at comets Halley and Grigg - Skjellerup measured by Giotto, and interplanetar…
