Yes, they found that the sun is connected to the Earth, at least our upper atmosphere is, via these "flux tubes". They give them terms but don't really understand what they are. I understand them as magnetic tunnels that allow the solar wind to stream into the poles and around the magnetosphere. Maybe the radiation belts too. The process of solar wind interaction with our atmosphere is itself not understood, they have no idea why we lose atmosphere and what happens to the plasma injected into it. It is very like a balance of charges. But plasma is relatively new in physics and there is still much to learn and understand how it all fits together, and it plays a major role in our atmosphere and therefore our climate and weather. So I find it laughable how they tried to perpetuate the global warming myth when in reality they know so very little about our climate they can barely predict the weather for the next day. If we understood it all then we can predict the weather far longer in advance and with extremely high accuracy, the more accurate and complete our understanding, the more accurate the predictions. When we understand something completely we can predict the outcome 100% of the time unless there are variables we can't observe.

The thing about plasma is it can be in 3 modes, invisible/dark mode where it is able to absorb EM frequencies due to dust, glow mode where it emits EM frequencies (like the sun and neon lamps) and discharge mode (lightning) where it discharges free electrons as sparks. What makes things even more complex is that any matter can be in the state of plasma and all plasmas have varying characteristics like density, temperature, number of electrons, the elements that comprise the plasma, the distribution and so much more. That is why it is so hard to create models for it. The calculations alone require some of the most powerful super computers to simulate.

The sun is an example of a dense plasma in glow mode, the solar wind is an example of a low density plasma in dark mode, CMEs are an example of a variable density (usually high) plasma in dark mode. There's plenty of youtube videos showing plasma in discharge mode, like plasma speakers. ALL plasmas emit electromagnetic radiation, that is why planets like Jupiter emit radio waves, why the sun and lightning emit all sorts of frequencies ranging from radio to gamma ray. Lightning is known to produce x-rays and sometimes gamma rays. Thunderstorms are known to accelerate particles into space and generate gamma ray flashes called terrestrial gamma ray flashes.

The very fact that 99.9% of the visible universe itself needs to be acknowledged by people outside the nuclear and plasma physics communities in order to begin to understand the universe and create a functional model of cosmology.
