Presentation Transcript

  1. Space Physics MHD Research Personnel: Jay R. Johnson Eun-Hwa Kim

  2. Key Issues: Entry and Transport

  3. Plasma Sheet Dynamics • How does mass, momentum and energy enter the magentosphere? • Reconnection • Kelvin-Helmholtz Instability • Kinetic Alfven Waves/Mode Conversion

  4. Plasma Sheet Dynamics • Entropy Definition global/total: S=p1/dv; specific/local: s = p/ • Entropy Crisis • Steady Convection • Substorm Transition • How are ions heated? • What convects cold plasma to the center of the plasma sheet? Mapping Technique

  5. Role of Heavy Ions • At Magnetopause • Reconnection (Threshold/Growth) • KH inertial effects (Inertial Scale Effects) • Mode Conversion (Strong Absorption) • At Planets • Mercury • Jupiter IIR AR
