I disagree that sunspot umbra temps, as low as 2500 K, are telling us that the 700 km Wilson depression takes us down into cooler plasma -- I think that the umbra is cooler for its own reasons. Remember that the temp on the limb is 4600 K, while perpendicular to the surface it's 6400 K. So at the top, it's 4600 K, and "somewhere below" it's 6400 K. If the temp is 2500 K at a depth of 700 km, then we go from 2500 to 6400 to 4600 K, all in 700 km. That can only mean that the temp is the result of some sort of energy conversion that occurs 3 times more robustly in the topmost 700 km. Your energy conversion is thermionic emissions from a solid iron electrode. That puts the electrode little more than 700 km below the visible surface. But then how are you going to get the hydrodynamic behaviors in the granules? These "make sense" as thermal bubbles that have to be at least as deep as they are wide (>1000 km), and more probably are 4x deeper (4000 km).upriver wrote:As I have mentioned in other posts i think the temperature is a combination of several events. [...] At the footprint of a loop you have the cold surface being plasmaized(new word) over some relatively short distance... The temperature rises from 1500K to 70,000K producing the iron plasma that comprises the loop... No body has ever explained why solar loops are made of iron plasma.
A similar hydrodynamic problem is the instances of s-waves in the visible surface after flares.

The crest-to-crest distance (i.e., wavelength) started at 6 Mm, and as the waves accelerated outward, in the last frame, it was 10 Mm. Just roughly speaking, I'd say that the trough of a 10 Mm s-wave would be at least 2 Mm below the equilibrium level, which means that there couldn't have been a solid surface at 700 km, or the wave would have bottomed out.
It would be easier to believe that the iron surface is 4800 km below the visible edge, as Michael contends, and then you toss the umbral temps as something to do with the sunspot itself, not temperature layering. You could even make the supersonic updrafts in the granules the consequence of your thermionic vaporization of iron, couldn't you?
Outstanding issues with the solid surface concept would still include differential rotation, supergranules, recharging (i.e., RF energy?), and the overall density (which would be too high if the whole thing was solid iron, so you need a low density core, but you also need it to produce the correct helioseismic shadows at .27 and .70 SR). I'm not saying that these couldn't be solved -- I'm just saying that they're problems.
As concerns the iron in the post-flare coronal loops, my model addresses this, so "nobody" needs to be changed to "only one other guy".
If the discharges were responding to a radial electric field, the field density would certainly be the greatest nearest the Sun. But this doesn't change the fact that the discharge channel would propagate backwards, from the Sun, out into the heliosphere. Is it possible to set a plasma lamp such that it just barely achieves arc mode, but doesn't arc all of the way out to the shell? In all of the relevant experiments that I've seen, as soon as the discharge steps up from glow to arc mode, the arc projects all of the way to the other electrode. So the radial field density isn't the critical factor -- it's the instability that causes arc discharges to get organized into discrete channels due to the magnetic pinch effect. In a plasma lamp, and in terrestrial lightning, the width of the channel remains consistent, even though the field density changes dramatically. Once the charges are pinched into a stream, the particle velocity is the same all of the way through, like water through a pipe.Siggy_G wrote:Its plausible that currents [into the Sun] are distributed accordingly. It is also plausible that there are internal dynamics that distributes energy. [...] The energy level of the emitted photons depends on the acceleration and interactions of the electrons emitting them, which in turn depends on medium density (interactions) and electric fields (acceleration). Both factors increase towards the Sun, peaking towards the surface, and are relatively weak and sparse throughout the heliosphere. Emissions accordingly.
Yes, in solar flares at the very least. And you're right that this does interesting things to the power requirements, but sustained fusion also places demands on the model in question.Siggy_G wrote:Does nuclear fusion/fission happen in the photosphere?

You're assuming the conclusion.PersianPaladin wrote:If the incoming current density is greater and across all surface areas, than you will get arc discharges everywhere rather than auroral phenomena just at the polar regions.
The incoming negative charge keeps the positive ions from coming out?PersianPaladin wrote:What holds back the positively charged ions? Well, Scott states that the lower photosphere with the high incoming negative charge tends to create a strong net inward negative electric-field force that restricts all but the most energetic ions to escape outward.
I was just referring to the general EU model, wherein the galactic (Birkeland) current powers the Sun. As concerns the conductivity, though they don't realize it, this is a requirement for the current to pass through the Sun, instead of through the surrounding interplanetary medium.justcurious wrote:I did not know that there was a Birkeland current "model", and I did not know that according to this model the Sun has a greater conductivity than the surrounding interplanetary medium. This is new and very interesting information, do you have a reference to the supporting data?
I'm not questioning whether or not the currents are there. But the model in question states that all of the Sun's power comes in through external currents. If that was the case, the "solar aurora" would be obvious.justcurious wrote:To me, the images of the corona do resemble the aurora.

I don't use the quantum mechanics "explanation" of black-body radiation. The general characteristics were defined by Kirchhoff, and I use Robitaille's theory of what causes it (as I stated in a previous post), which is not QM.justcurious wrote:So why do you use Blackbody radiation in your explanations if it's quantum-babble?
Here's what I actually said (offline)...justcurious wrote:You're breaking the deal of no walls of text, and max 1 or 2 points.
So I'm trying to be more succinct, refraining from elaborating, and not opening up too many new tangents. I elaborated a bit on the black-body issue, because it's a crucial topic in stellar/solar theories, and I saw that you were quoting mainstream sources as if they were reliable, and I thought I'd save you some trouble by giving you the heads-up. Sorry. You still twisted my words around, and blamed me for it. Then, when I don't elaborate, you say things like, "I'm sorry but I disagree, I don't find your explanation straightforward at all. Torsional oscillation... Is it your own theory?" So it's my fault that you don't know what torsional oscillation is? Or is it my fault that I didn't elaborate? But then it would have been my fault for explaining without being asked. Hmmm, I don't think that this is my problem. Please just go in your Control Panel and block me. Or just don't read this thread anymore.CharlesChandler wrote:Some people are following my work closely, and appreciate it when I elaborate, while others are not so interested, and wonder why I take up so much space on some of these threads. When in doubt, if I wait until asked before answering, it should cut down a bit on the clutter.
To the others on this thread, I'm striving to be more succinct. If I see open issues, I'll respond briefly. If I don't make sense and you consider it to be important, just let me know what doesn't make sense. If you want to make personal comments, PM me.
