A joint study of Solar Orbiter first data and PSP E5 through 3D MHD modeling
Abstract
The first remote sensing window of Solar Orbiter started mid-June 2020. After a successful commissioning, Solar Orbiter in situ instruments were then continuously monitoring. This window is coincidentally close to the fifth perihelion of Parker Solar Probe. This offers an opportunity for a joint study between the two probes' data. We use a 3D MHD model of a turbulence driven solar wind, and compare the structure of the inner heliosphere obtained by the model and the available in situ and remote sensing data of the spacecraft. We discuss the key features of the model and tricky points that require care, such as the choice of the input magnetogram. In particular, we notice the strong influence of two active regions on the magnetic sectors and solar wind properties. These regions will be increasingly important features in future encounters and joint studies as we go towards solar maximum.
