Energetic Particle Observations
Space Science Reviews, 2006The characteristics of solar energetic particles (SEP) as observed in interplanetary space provide fundamental information about the origin of these particles, and the acceleration and propagation processes at the Sun and in interplanetary space. Furthermore, energetic particles provide information on the development and structure of coronal mass ...

The emission of energetic particles from the Sun is one of the major manifestations of high energy astrophysics and is related to a variety of astrophysical and geophysical phenomena in the heliosphere. An event of solar energetic particles (SEP) is seen as a sudden rise of the counting rate of the background galactic cosmic rays reaching a high value ...

Energetic particle experiment ERNE
Solar Physics, 1995The Energetic and Relativistic Nuclei and Electron (ERNE) experiment will investigate the solar atmosphere and the heliosphere by detecting particles produced in various kinds of energy release processes. ERNE is at the upper end in energy among the SOHO particle instruments.

Energetic Particles at High Latitudes
Space Science Reviews, 1995We review work on diffusion coefficients of energetic particles with an attempt to extract implications on their behaviour at high latitudes. In the ecliptic plane results from solar energetic particle propagation between the Sun and about 5 AU can be described by an effective radial mean free path λ r which is approximately constant as a function of ...

Some observational aspects of solar energetic particles (SEPs) are briefly discussed. The shift from the flare paradigm of SEP origin through the two-class paradigm of impulsive and gradual SEP events to hybrid events is described. Comprehensive investigations of coronal mass ejections (CMEs) and solar energetic particles during the SOHO era have shown

Energetic particles recorded in the Earth environment and in interplanetary space have a multitude of origins, i.e. acceleration and propagation histories. At early days practically all sufficiently energetic particles were considered to have come either from solar flares or from interstellar space.

Energetic particle composition
AIP Conference Proceedings, 2001Abundances of elements and isotopes have been essential for identifying and measuring the sources of the energetic ions and for studying the physical processes of acceleration and transport for each particle population in the heliosphere. Many of the sources are surprising, in a few cases the acceleration bias is extreme, but an understanding of the ...

Energetic Particle Acceleration
2016We have seen that the Sun is a transient source of energetic particles. The production is modulated by the 11 year solar cycle, especially at high energies. At times of solar flares it is clear that there is significant transient acceleration going on in the solar atmosphere, in or above the photosphere, with energies occasionally reaching to 100 MeV ...
