Journal ArticleDOI
Coronal phenomena at the release of solar energetic electron events
TL;DR: In this article, the authors investigated the relationship between coronal acceleration and the escape of electrons to interplanetary space using radio, EUV and X-ray observations, and concluded that the combination of time-extended acceleration at heights ≲ 0.5 ǫ above the photosphere with the injection of electrons into a variety of closed and open magnetic field structures explains the broad variety of timing shown by the radio observations and the in situ measurements.
Journal ArticleDOI
Coronal γ-Ray Bremsstrahlung from Solar Flare-accelerated Electrons
TL;DR: The Reuven Ramaty High Energy Spectroscopic Imager (RHESSI) provides for the first time imaging spectroscopy of solar flares up to the γ-ray range as mentioned in this paper.
Journal ArticleDOI
Solar energetic electron events and coronal shocks
TL;DR: In this paper, a detailed investigation on the origin of such electrons is presented for four particlular solar events, and it is concluded that mildly relativistic electrons at 0.25{0.7 MeV energies measured in the interplanetary medium from solar energetic particle events are accelerated by coronal shock waves, commonly in association with white-light CMEs.
Journal ArticleDOI
Two Classes of Solar Proton Events Derived from Onset Time Analysis
Säm Krucker,Robert P. Lin +1 more
TL;DR: In this article, the authors analyzed the onset times for 26 solar energetic (from 30 keV to 6 MeV) proton events that exhibit clear velocity dispersion, as observed by the three-dimensional Plasma and Energetic Particles experiment on the Wind spacecraft.

TL;DR: In this paper, Fermi-LAT was used to detect three behind-the-limb (BTL) solar flares that occurred on 2013 October 11, and 2014 January 6 and September 1.
