Abstract: | A solar flare is a violent and transient release of energy in the corona of the Sun, associated with the reconfiguration of
the coronal magnetic field. The major mystery of solar flare physics is the precise nature of the conversion of stored magnetic
energy into the copious accelerated particles that are observed indirectly by the radiation that they produce, and also directly
with in situ detectors. This presents a major challenge for theory and modeling. Recent years have brought significant observational
advances in the study of solar flares, addressing the storage and release of magnetic energy, and the acceleration and propagation
of fast electrons and ions. This paper concentrates on two topics relevant to the early phase of a flare, magnetic reconnection
and charged particle acceleration and transport. Some recent pertinent observations are reviewed and pointers given for the
directions that, this reviewer suggests, computational models should now seek to take. |
