Project: Solar Wind Turbulence from In-Situ Observations with Solar Orbiter

The solar wind is a stream of energetic particles from the Sun, which for example causes the aurora when interacting with Earth’s magnetosphere. In extreme cases it can severely impact satellites for example, therefore it is included in the National Risk Register. The solar wind is a low-density plasma with high Reynolds number. As in any fluid-like medium, the solar wind exhibits turbulence, a non-linear phenomenon. And it can be observable in for example smoke as swirls, also called eddies. As these swirls break up into smaller swirls which again break up into smaller ones and so on, the energy of one big swirl gets transferred into smaller swirls, which forms the turbulence cascade.

Solar Orbiter, a satellite by NASA and ESA launched in 2020, which is orbiting the sun and taking measurements from within the solar wind, provides us with an unprecedented opportunity to study turbulence. As Solar Orbiter is reaching into orbits closer to the sun than ever before, we can use the solar wind as large scale laboratory for plasma dynamics to study the characteristics of turbulence and its evolution with distance from the sun. We use measurements from the Magnetometer (MAG) and the Solar Wind Analyser Suite (SWA).

This project studies two mechanisms which are proposed to mediate the energy cascade – coherent structures and waves. To distinguish these two we are modelling and adapting current data analysis methods to apply them to the in-situ measurements.
