Context studies of Parker Solar Probe and Solar Orbiter flybys using synthetic in-situ and remote-sensing observations

We use the Space Weather Modeling Framework's Alfvén Wave Solar atmosphere Model to simualte the origin and evolution of solar wind plasma during multiple SO and PSP flybys.   Synthetic spectral and narrow band imaging, synthetic spectra and in-situ plasma data are used to study the heating and acceleration of the coronal plasma and solar wind in the inner heliosphere. We identify large scale structures the spacecrafts pass through: current sheet crossings, plasmas of different origins. When data is available we simultaneously simulate non-equilibrium ionization of minor heavy ions in the solar wind along the SO trajectory and study how the plasma charge states represent the different origins of solar wind and also how the out-of-equilibrium charge states change the synthetic remote sensing observations compared to using equilibrium assumptions.
