Solar Orbiter data reveals common feature of organised regions of plasma flow in solar wind
Behind the chaotic, turbulent flow of the solar wind — a plasma stream ejected from the sun’s corona — are organised regions of flow known as coherent structures. Now, researchers have discovered a common characteristic of these structures that provide insights on their role in heating and driving solar wind.
Using data from the Solar Orbiter probe, the team studied solar winds at heliocentric distances between the orbits of Mercury and Earth across a range of plasma parameters. From these analyses, they identified a common threshold beyond which the coherent structures exist — implying that the mechanism governing them is consistent regardless of the distance from the sun or the nature of the plasma.
