Plasma flows in different magnetic environments on the Sun
Abstract
The Sun, as a magnetic star, has dynamics and complex structures on all scales. There are flows throughout the solar atmosphere from the surface to the outer solar atmosphere (and into the solar wind). In this review, we will discuss from the smallest scale flows seen, to the most dramatic flows in coronal mass ejections. The smallest scale phenomena such as jets, plumes and small brightenings such as those seen in the Solar Orbiter 'campfires' all have possibilities to flow into the solar wind. The latest results from Parker Solar Probe has provided tantalising predictions of when the magnetic switchbacks seen in the solar wind originate - on the network boundaries where many of these small-scale flows are seen. Moving to the large size scale flows, with the large flares, and coronal mass ejections, the flows start in the pre-trigger phase on a small size scale, and expand across the Sun, creating a huge impact in the solar wind. The current status will be reviewed.
