TEAM WORKSHOP

Solar/heliospheric sources of suprathermal/energetic particles throughout the solar cycle

First meeting: 11 to 15 April 2005

Second meeting: 23 to 31 March 2006

Third meeting: 11 to 15 June 2007

ISSI, Bern, Switzerland

Abstract

The relative importance of energetic particle sources in the Sun and further out in the heliosphere is still poorly understood. Solar-heliospheric particle acceleration is intimately related to reconnection processes, as well as to shocks and turbulence on various scales. Small solar flares may play a major role in coronal heating and in giving rise to the solar wind, while large flares and CMEs have impact on space dosimetry and may even influence life on geological time scales. An earlier ISSI Team Project (No. 2, in 1997) on quiet-time protons is now proposed to be extended to active periods, to other species, to lower energies, and to heliospheric radial and latitudinal positions far from the Earth orbit. Both spectral features (e.g. suprathermal tails, spectral minima) and intensity distributions will be studied at various phases of the last few solar cycles. Particular emphasis will be given to solar flare and CME particles in the inner heliosphere. Attempts will also be made to better understand the origin of solar-heliospheric particle populations in terms of modern non-equilibrium statistical mechanics and thermodynamics. The team adopts a truly interdisciplinary, comprehensive approach towards those problems.
