A Need for a Science of Heliophysical Plasmas “It cannot be emphasized too strongly that the development of a solid understanding of the magnetic activity, occurring in so many forms in so many circumstances in the astronomical universe, can be achieved only by coordinated study of the various forms of activity that are accessible to quantitative observation in the solar system. ” E. Parker Cosmical Magnetic Fields
Ingredients of a NESSC Comparative Study of Explosive Energy Conversions 1. CME/substorm initiation 2. ICME/plasmoid transport 3. Roles of magnetic reconnection (preexplosion, post explosion) 4. Particle heating and acceleration 5. Flares and auroras 6. Your thoughts here 7. And here
