Solar energetic particle (SEP) events are characterized by large enhancements of particle fluxes above the background levels from the Sun, including protons, electrons, and heavier nuclei with energies ranging from a few keV up to GeV. It has been widely accepted that solar flares and coronal mass ejections (CMEs) are the major solar explosions producing energetic particles. However, how solar flares and shocks (CME-driven or interplanetary) affect SEPs is still an unresolved problem due to the complexity of acceleration, dissipation, and transport processes involved in an SEP event. Among the electromagnetic spectrum, the radio emission is particularly used to diagnose the particle acceleration and transport processes in solar atmosphere or in the interplanetary space, and thus can provide information on the dynamic properties of energetic electrons in solar explosions. Students in the summer program will analyze the solar type II and type III radio bursts, which are produced by the CME-driven/interplanetary shock and magnetic reconnection, as well as the time-variation profile of SEP flux. In addition to the data analysis, students can learn the magnetic reconnection and particle acceleration theories related to the solar eruptive phenomena, and the knowledge about SEP.
