Physical Description of Various Coronal Structures

  1. Construct empirical models of coronal holes which specify particle temperatures, densities, outflow velocities and abundances.
  2. Construct empirical models of streamers which specify particle temperatures, densities, outflow velocities and abundances.
  3. Construct empirical models of quiet coronal regions which specify particle temperatures, densities outflow velocities, and abundances.
  4. Construct empirical models of streamers with an adjacent coronal hole.
  5. Construct empirical models of coronal holes, streamers, and quiet coronal regions at the base of the corona (1 R < R < 1.5 R).
  6. Use synoptic observations and tomographic techniques to determine local values of coronal plasma parameters.
  7. Use observations over a prolonged period to study the morphology of various coronal structures.
  8. Measure temperatures, densities, and outflow velocities of protons, electrons and minor ions in fine scale structures such as polar plumes and the closed loops and open field structures of helmet streamers.
  9. Measure temperatures, densities, particle outflow velocities and abundances in CMEs.
  10. Measure neutral hydrogen temperatures in coronal holes at heights above 3 solar radii.
