Chen B Bastian TS Shen C Gary DE Krucker S Glesener L 2015 Solar flares--the most powerful explosions in the solar system--are also efficient particle accelerators, capable of energizing a large number of charged particles to relativistic speeds. A termination shock is often invoked in the standard model of solar flares as a possible driver for particle acceleration, yet its existence and role have remained controversial. We present observations of a solar flare termination shock and trace its morphology and dynamics using high-cadence radio imaging spectroscopy. We show that a disruption of the shock coincides with an abrupt reduction of the energetic electron population. The observed properties of the shock are well reproduced by simulations. These results strongly suggest that a termination shock is responsible, at least in part, for accelerating energetic electrons in solar flares. application/pdf https://sonar.ch/global/documents/208798 eng info:eu-repo/semantics/altIdentifier/doi/10.1126/science.aac8467 info:eu-repo/semantics/altIdentifier/pmid/26785486 info:eu-repo/semantics/openAccess Science (New York, N.Y.). - 2015 Multidisciplinary Particle acceleration by a solar flare termination shock. http://purl.org/coar/resource_type/c_6501
