Radial and Latitudinal Variations of the Energetic Particle Response to ICMEs
Lario, D.
We present energetic particle observations during events in which the interplanetary counterpart of a single coronal mass ejection (ICME) has been observed by spacecraft widely separated in radial distance and latitude. The effects that ICMEs have on energetic particle intensities depend on (1) the ability of ICMEs to drive strong shocks able to a…
KET Ulysses Observations of SEP in and out of the Ecliptic
Heber, Bernd; Struminsky, Alexei
Observations of eight solar energetic particle (SEP) events in the polar heliospheric regions and six events near the Jupiter orbit and their implications for the current paradigm of particle acceleration and propagation in the heliosphere are discussed. These events are easily identified with well-known episodes of the solar activity in 1992, 199…
Radio Emissions from the Planets and their Moons
Zarka, P.
We review the present observational knowledge of planetary non-thermal radio emissions (spectrum, emitted power, source location, beaming, modulations and frequency-time structures), emphasizing high-latitude, auroral and satellite- induced components at the outer planets. Important results have been obtained in the past few years from the observa…
The Role of Reconnection in the Formation of Flux Ropes in the Solar Wind
Gosling, J. T.
New magnetic loops formed in the corona beneath coronal mass ejections, CMEs, provide strong evidence that magnetic reconnection commonly occurs within the magnetic `legs' of the departing CMEs. Such reconnection is inherently 3-dimensional and produces a magnetic flux rope structure within a CME. Depending upon how far reconnection proceeds, the …
Measuring Plasma Parameters With Thermal Noise Spectroscopy
Moncuquet, Michel; Issautier, Karine; Meyer-Vernet, Nicole +4 more
This paper describes the basic principles, the unique features and the limitations of thermal noise spectroscopy as a tool for in situ diagnostics in space plasmas. This technique is based on the analysis of the electrostatic field spectrum produced by the quasi-thermal fluctuations of the electrons and ions, which can be measured with a sensitive…
Using energetic particles to probe the magnetic topology of ejecta
Richardson, I. G.
Observations of energetic particles over a wide range of rigidities can provide information on the presence of ejecta, and their structure. A large fraction of ejecta produce a local, few percent depression of the cosmic ray density. The depression typically extends over the ejecta region as determined from a range of ejecta signatures, in particu…
