It looks into the heating mechanism of the corona which is in the millions of degrees.
This remains a problem with mainstream astronomy due to the much lower temperature of the photosphere at around 6,000 degrees Celsius.
The paper:
That magnetic fields play a dominant role in heating the sun's corona is now widely accepted in solar physics. However, it remains controversial whether this effect is mainly due to a sudden change in magnetic field structures in the solar plasma or to the dampening of different types of waves.
I assume the "magnetic canopy" is the chromosphere."Just below the sun's corona lies the so-called magnetic canopy, a layer in which magnetic fields are aligned largely parallel to the solar surface.
As I have proposed elsewhere the chromosphere is a double layer.
Thus ,in my view, the condensing plasma (and high energy particles from the interstellar medium) coming from as far away as the heliopause in towards the sun is in large part stopped by the chromosphere. The double layer is working.
However, there is current passing through the chromosphere. The quote above about the magnetic fields aligned largely parallel to the solar surface indicates currents passing out (and into) the solar surface. The lowest temperature in the sun is about 4,300 degrees, is within the chromosphere, and is an indication of the more highly aligned currents crossing the double layer boundaries.
So, the incoming plasma is largely turned back by the double layer which causes great chaos as it turns at the base of the corona and slams into the continuing incoming plasma. This plasma logjam is the reason for the million degree temperatures found above the chromosphere in the near corona atmosphere of the sun. It also explains observed sudden changes in magnetic fields or dampening of Alfven waves discussed in the paper.
The electric plasma nature of the three main parts of the sun (photosphere, chromosphere, corona) generally supports the EU model of our solar system but IMO does not support the so called electric discharge as presented by Thornhill and Scott. There are similarities with the Crooks tube in lab settings, and similarities with the Safire project experiments. However, both are supplied different voltage potentials from a separate connection to an EXTERNAL voltage source at each side of the electrical equation, or circuit.
With the sun, all the electrical charges come from the same source...the condensing plasma within the solar system in addition to high energy particles from outside the solar system. The inner body of the sun no doubt gets charged by the process but does not enjoy a separate electrical connection from whatever is happening at the heliopause. To describe the sun as an anode (or cathode) is misleading in general and in particular continues the need for, and search for, the solar CIRCUIT.
The sun is a free space organic phenomena.
The plasma has the ability to separate charge,
to organize the separated charges into large structures,
and do work (in the physics sense).
One thing plasma does a lot is condense about large suitable bodies in space,
and form structures we call stars.
