Scientific Aims
Current Sheets (CSs) are a basic prerequisite for magnetic reconnection. The goal of the proposed research is to define CS properties in the solar athmosphere and their signatures in the interplanetary medium, and to understand their role in the developments of solar eruptive events. The project was inspired by recently acquired ground and space based observations that reveal CSs signatures at the time of flare/CMEs (Coronal Mass Ejections), in the chromosphere, in the corona and in the interplanetary medium. At the same time, theoretical studies predict the formation of CSs in different models/configurations, but theories and observational results have not yet developed an interaction efficient enough to allow us to construct an unified scenario. This proposal aims at maximizing the synergy between observers/data analysts and theoreticians, so as to enable a significant advance in our understanding of CS behaviour and properties. A further motivation for studying CSs is related to the expected electric fields in CSs that may well be the source of solar energetic particle (SEP) events that create a serious hazard for human being and their machines. Hence, the refinement of CS models has a pragmatic benefit in helping forecast the production of energetic particles, an issue of growing importance for our present society. Our project also fits perfectly into the scope of the International Heliophysical Year (see, an international program devoted to understanding the entire interconnected heliophysical system by fostering collaborations among scientists from different countries and specialties.
