Solar flares and energetic particles.
Solar flares are now observed at all wavelengths from γ-rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares. Energetic electrons and ions interact with the solar atmosphere and produce high-energy X...
متن کاملObservations and Interpretations of Energetic Neutral Hydrogen Atoms from the December 5, 2006 Solar Event
We discuss recently reported observations of energetic neutral hydrogen atoms (ENAs) from an X9 solar flare/coronal mass ejection event on 5 December 2006, located at E79. The observations were made by the Low Energy Telescopes (LETs) on STEREO A and B. Prior to the arrival of the main solar energetic particle (SEP) event at Earth, both LETs observed a sudden burst of 1.6 to 15 MeV energetic ne...
متن کاملAcceleration and Propagation of Solar Energetic Particles
The acceleration of electrons and charged nuclei to high energies is a phenomenon occuring at many astrophysical sites throughout the universe. In the heliosphere, processes in the solar corona associated with flares and coronal mass ejections (CMEs) are the most energetic natural particle accelerators, sometimes accelerating electrons and ions to relativistic energies. The observation of these...
متن کاملAcceleration of solar energetic particles: the case of solar (ares
Solar energetic particles are believed to originate from two di*erent sources, solar (ares and coronal mass ejections. These two sources are the most energetic particle accelerators in the heliosphere, as they can accelerate electrons from 10 keV to a few MeV and protons from a few MeV to a few GeV. In this contribution, we restrict our presentation to the case of solar (ares, by reviewing the ...
متن کاملCarrington Flare of 1859 as a Prototypical Worst-Case Solar Energetic Particle Event
Recent analyses of ice core samples indicate that the Carrington flare of 1859 was the largest event observed in the past 500 years. These ice core data yield estimates of the proton fluence for energies greater than 30 MeV, but provide no other spectrum information. Assuming that the proton energy distribution for such an event is similar to that measured for other recent, large events, total ...
