2.3.2 What are the properties and distribution of heliospheric shocks?

Children Display

  • Understand coronal conditions under which the shocks form and determine the interplanetary conditions where they evolve.
  • Identify interplanetary shocks and characterise their spatial and temporal evolution. Characterize shock structure and determine whether they are locally quasi-perpendicular or quasi-parallel, and study kinetic properties of shock-related waves and turbulence that control ion scattering mean free paths near the shock. [IS only]
  • Study heating and dissipation mechanisms at shocks with radial distance.
  • Identify mechanisms that heat the thermal solar wind particle populations near shocks and determine their energy partition.
  • (To be moved in the activities section: Correlate coronal shocks passage with in situ measurements: METIS visible-light and UV observations of the shock in corona together with RPW measurements of type II radio bursts).


Required observations:


  • 5 min captures

Other constraints:

  • Good radial spread.
