Event description:

In solar eruptive events, a large amount of stored magnetic energy is converted to thermal energy of hot plasmas and to kinetic energy of ejected matter and energetic particles. A significant fraction of the energy released is contained in nonthermal electrons and ions, which implies a pressing need to identify and understand the responsible energy release and particle acceleration processes. The most direct signatures of energetic particles at the Sun are observed in the gamma-ray, hard X-ray and radio regimes. These observations are complemented by imaging and spectroscopic data in the soft X-ray, (extreme) ultraviolet, and visual ranges, as well as by in-situ observations of solar energetic particles. A theoretical understanding of the physics of solar eruptions can only be achieved by considering all these different observational constraints. Therefore, the event will have an emphasis on complementary multiwavelength observations of eruptive events.

Some of the topics to be discussed are constraints on particle acceleration from hard X-ray, gamma-ray and radio observations, particle transport models, spectroscopic information on flare plasma heating, new insights into CMEs from STEREO, and in-situ observations of solar energetic particles. A special session will be dedicated to the respective roles of energy release and particle acceleration occuring on large and small spatial scales, respectively. This event is sponsored by the German Aerospace Center DLR.
