OP "Solar"
Just organizing some thoughts:
Michael Mozina wrote:
The problem is that electric current, gravity wells, and magnetic fields tend to cause plasmas to separate. If there is any sort of plasma separation going on in the sun, then their "assumptions" are critically flawed, and therefore the composition issue is also flawed.
This simulated image and it's accompanying "running difference" has been my "Picture that won't go Away" in contrasting EU with the 'Sun has a Surface' model.

It's very difficult to explain the 'structural' features as they progress over time in any other way; and I've been trying to reason it out. I've been trying to figure out: If the sun is a ball of lightning/plasma without a surface then how is that so from a plasma perspective? It seems that if a ball of lightning were the case for our Sun then we would see a very powerful plasmoid with no encasement such as the jaw dropping and utterly magnificent Sag A* which lies at the center of the Milky Way (what black hole?).
Sag A* is one of my all time favorite celestial features and to me looks to be a pure unrestricted plasmoid of immense proportions and power. A smaller scale version is what I sometimes consider to be at the center of the Sun.
Stratification is not a new thing insofar as plasmas are concerned as operative terms in relation to the dynamics of it's amorphous hierarchical characteristics would testify:
Hysteresis: a type of non-linear 'lag' as relates changes in multi connected systems.
Multifurcation: a type of hierarchical 'branching' of structures/systems
Adiabatic: 'lag' or 'lapse' rate at which the temperature of a fluid changes when subjected to changes in pressure.
Hydrostatic Stratification: which also deals with "fluids at rest or to the pressures they exert or transmit".
Thermal Stratification: "The formation of layers of different temperatures"
Chemical Stratification, Centrifugal Stratification and so on.
But there are also ideas of '
magnetic' stratification' to which I would add the prefix electro- always. This habit of using 'magnet' without citing it's electrical prefix should be outlawed across the scientific spectrum. In relation to the fact that electricity has a powerful impact on the dynamics of plasmas 'electromagnetic stratification' seems an important option when considering the layering of plasmas. Especially in light of the fact that...
"
...the introduction of magnetic fields into a plasma makes a certain (not perfect but important) insulation of macroscopic field( or wave, or fluid) motion from microscopic particle (or kinetic) motion. This partial detachment of the fluid motion from the thermal energy is one of the main reasons why so many interesting phenomena in magnetized plasmas emerge..." - Plasma Astrophysics Tijima/Shibata
The above mentioned "insulation" seems to be that which conveys the 'self organizing' characteristic of plasmas. Which may also say a lot in relation to the thermal verses the accelerated aspects of the solar "wind". That this "wind" demonstrates acceleration qualities that are thermal but also those that are electrical would seem a testament to the above.

This oscillation is centered around r = 0.99R⊙ with a width of about 0.03R⊙. This anomaly is composed of two parts: the first, below r = 0.99R⊙, is in phase with the solar cycle and has a maximal amplitude of about 10 km; the second part above r = 0.99R⊙, is in antiphase with the solar cycle and reaches larger amplitudes, of about 26km. These variations indicate the presence of a changing with the solar cycle of a physical structure that could be described as a very thin transition layer...
"...changes in the stratification with the inner layer (below 0.99R⊙) moving up during the increase of activity (compression) and the outer layer (above 0.99R⊙) moving down (relaxation). The precise localization of these layers isuncertain because have a characteristic width of about 0.005R⊙.""
Changes in...stratification of the Sun
I find these oscillations interesting in relation to the z-pinch. Not that this is what causes the cycle. But as follows:
If a z-pinch produces a Sun or sphere then it would seem that at some point a state of relative equilibrium would be reached with so called 'dusty plasma' dampening the power of both the compressive affect with the expansive affect. This would seem to be a process that would not, once relative equilibrium had been reached, subsequently cease. It would also seem that a natural consequence of the process would produce an aggregate equipotential 'ring' and/or 'rings' of compressed matter/plasma. In other words z-pinch electromagnetically stratified 'shells' or layers' that could be 'insulated' from their thermal, pressure, and perhaps magneto-centrifugal equivalents.
In light of the "insulating" or "self organizing" characteristics of plasma via density, pressure, charge what have you - has, or was, consideration given to the idea that the stratification observed could be the result of
double layers which can "
separate regions of plasma with quite different characteristics."?
Sometimes, it seems, double layers are associated more with their dynamic explosive aspect more so than with their quite seperatrix nature. When it comes to stratification it would seem the later to be just as relevant. Your thoughts on that greatly appreciated as well.
That probably could have been much shorter but such is pondering.
