Electric Sun's Light
This video is about the progression of a solar model by Ralph Juergens to one by Don Scott for an Electric Sun.
It is unfortunate Pierre-Marie Robitaille did not participate near the end of this discussion. He has a different model for a Sun, though also driven by an external current from the galaxy.
Around 7:29 - Don mentions tufts in the photosphere.
Unless I am mistaken, the tufts are in the chromosphere, the plasma layer above the actual solar surface, the photosphere.
Sometimes Don seems to make no distinction between the two distinct layers.
Around 7:40 - the figure identifies the photosphere as the "base" and the chromosphere as the "collector" in this circuit. They are not the same layer here.
Around 8:26 - Don makes the following statements:
Where does the light come from?
Where does all the light from the Sun come from?
It comes from the recombination of those electrons.
If you look at a star's spectrum, there's the absorption lines and emission lines.
The emission lines are the bright lines.
The light comes from the recombination.
There is a major problem here.
If I look at a star's spectrum, it has the wavelength distribution of thermal radiation where the wave length at the highest intensity is related to the "black body" temperature.
The European Southern Observatory has a web page titled Library of Stellar Spectra
offering a multitude of gif files with spectrograms of many star types.
Stars exhibit of spectrum of thermal radiation which is shown in these files.
All Absorption and emission lines come from atoms in the line of sight to the light source.
There are few, if any, emission lines in this collection. Absorption lines are frequent, often from the hydrogen Lyman or Ballmer series.
The light from the Sun or from a star is not from emission lines.
The absorption lines which Don mentions are missing wavelengths in the thermal radiation spectrum. Those lines contribute nothing.
The light from the Sun comes from the photosphere, as its name implies.
Robitaille described how the heat is transfered from the hot solid core, through the liquid convective zone, to the liquid photosphere which tries to cool by emitting thermal radiation.
Above the photosphere is the chromosphere where all the behaviors described by Don occur.
The emission lines occuring in either the chromosphere or the E-corona are a minimal contribution to the total solar radiation.
Unlike Don's statement, the bright light from the Sun does not come from emission lines. Also, most emission lines are in ultraviolet, not in optical.
The measured temperature for stars is in a thermal radiation distribution which includes the visible wave lengths.
This is the way I see this progression which began with Juergens.
Ralph Juergens recognized the Sun having a fusion core failed to match the observations for sunspots and the chromosphere in general..
He developed the initial Electric Sun model for the observed chromosphere behaviors. In a paper title, I recall he called the photosphere the bottom of the Sun rather than the top.This title is just emphasizing the chromosphere. The sunspots are clearly not driven by a fusion core.
His model does not explain the photosphere temperature. At the time, for a "gaseous sun" the photosphere was considered a layer in atmosphere, not a physical surface. Robitaille makes that distinction.
As Robitaille tells his story, using helio-seismology he developed a model based on metallic hydrogen, as a condensed matter building block, from the core all the way out to the corona. He explains all the solar observational data to the corona. However, he did not explain the transmutation process happening on the photosphere though he explained how those non-hydrogen elements developed intercholate regions within the photosphere, and how they are ejected in the solar wind.
Don is right about some behaviors below the photosphere like the axial current heating the core and the sub-surface loop currents affecting the suspot cycles in the chromosphere.
Don and Wal are correct in using SAFIRE results for improving our understanding of the chromosphere.
Don does not explain the observed stellar spectrum showing thermal radiation from the photosphere temperature.
No star has a spectrum dominated by emission lines. The various absorption lines are used for classifying a star type.
He is wrong about the bright light from the Sun coming from the chromosphere rather than the photosphere.
The Thunderbolts Project agrees the Sun is not powered by fusion but disagrees on how a star radiates the observed light.
