The "structures" of the photosphere change on roughly 8 minute intervals. RD images of the photosphere do not show this type of rigity. How come these structures we see in iron ion wavelengths last for hours, days, and weeks? Why do we see no evidence of differential rotation in these images as we find in helium filter RD images? What is that "structure" we see in Kosovichev's Doppler image? Why aren't the shapes of these rigid features affected by the CME event? </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Which means nothing when you consider that the sun about a million miles across.</DIV></p><p>Size is a relative factor. There is plenty of differential rotation seen in helium filter images from the same instruments on the same satellites, at the same resolution. Why do the iron ion lines images produce a set of rigid, long lasting structures whereas no other filter produces this same effect? Size is factor of course, but there is more to the story than simply size. If size were the only issue, the the helium ion images would show us similar results would it not? </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Spectragraphic evidence point towards gaseous states (thus the emission and absorption spectra) and pressures,</DIV></p><p>Spectroscopic evidence is subject to interpretation. A lot of what we might hope to get from this information depends entirely on the model that is selected to begin with, and the 'assumptions" that we begin with. If we "assume" a mass separated model, we have to take into account the various layers of the atmosphere. If we begin with a non mass separated model we might interpret such spectroscopic data entirely differently. The spectroscopic data is open to significant interpretation as it relates to determing overall solar composition.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>doppler shifts,</DIV></p><p>Take a look at the tsunami tab of my website and you'll notice that the Nickel ion Doppler images show the same riid features, and they reveal the location of these rigid features in relationship to the surface of the photosphere. Specifically we can see rigid features exist under the surface of the photopshere, at a very shallow depth under the surface of the photosphere. No doubt these rigid features are located at the "stratification subsurface" seen in the heliosiesmology data.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>etc that don't match with solids.</DIV></p><p>What' is causing those sound speed changes in the stratfication subsurface?

Okay, I'll buy that...but the atmospheres aren't over 5,000 degrees.</DIV></p><p>The temperature of the atmosphere is going to be affected by the amount of current running through the atmosphere. When discharges occur in th Earth's atmosphere, we observe x-rays and gamma rays. We observe that larger physical bodies like Saturn experience far more powerful electrical discharges than the Earth. When we point Rhessi at the sun, we see gamma rays like we see from Earth's discharges in Rhessi instruments and we observe a constant stream of x-rays coming off the sun. Dr. Charles Bruce even documented the propogation speed correlations between discharge speeds in the Earth's atmosphere, and discharge speeds in the solar atmosphere. The turbulance in the atmosphere is directly related to the amount of overall energy flowing through the system. The Earth experiences discharges that release x-rays and gamma rays. Saturn has more powerful atmospheric discharges. The sun is obviously the focal point of mass in the solar system and it experience the bulk of the current flow, and therfore experience the most electrical atmospheric activity. There is no other empircally verified way to explain these high energy events in the solar atmosphere. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The sun is vastly more massive,</DIV></p><p>Because it is more massive, it carries a more massive load of the current flow the flows through our solar system. that is why we see the termperatures in the corona soar to millions of degrees. Electrical discharges are known to heat plasma to extreme termperatures and emit gamma radiation. That is what we observe in the solar atmosphere. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>has an insande energy output. </DIV></p><p>How can you be certain that all the energy output is internally driven? The big plus for hydrogen sun theory is that it theorectially *could* power the sun internally, and still last for billions of years. An external energy source would also allow the sun to shine for billions of years. How do we know for sure if it's one or the other, or a combination of both internal and external energy sources that are responsible for the sun's total energy output?</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>It's mass and average density, btw, match up very, very well with the 75% hydrogen 25% helium figures. </DIV></p><p>Well, that really just tells us an "average" density, which is actually closer to water than to hydrogen. We can't use that average density figure to claim it's made of water. It's average density only tell us it's average density, not it's composition. The internal arrangement of elements will ultimately determin it's average density. If we looked at the average denisity of that water shell with an air bubble inside from the Nasa images, we can see that the density of the outer shell is substantially more dense than the air inside the water shell, and more dense than the average density of the total system. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>It doesn't match so well with it being iron. </DIV></p><p>It doesn't match well with a *solid* sphere made of iron. That isn't what I'm proposing however. Even by our calculations, the sun is not a solid iron sphere.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Throw in simple things like convection, which is easily demonstrated as possible/probable when you due the equations assuming hydrostatic equilibrium (a very well founded assumption btw), and it being liquid/plasma makes sense too.</DIV></p><p>Ya, but that stratiifcation subsurface sitting in the middle of your presumably open convection zone sort of blows that theory out of the water. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>It also doesn't behave like a solid, with the equatorial regions rotating faster than the poles,</DIV></p><p>Show me some RD iron ion images that demonstrate that the poles rotate faster than the equator. I'm sure you can do that with plasma layers like the photopshere, but you can't do that with the stratifcation subsurface. It rotates uniformly from pole to equator. That's one of the big problems you'll run into trying to explain various RD images in different wavelengths. Photosphee activity shows clear signs of differential rotation, and plasma movement galore because the photons we observe are mostly coming from the photophere plasma and it's moving around. The iron ion wavelength's on the other hand are mostly coming from coronal loop activity, and they are being reflected off of that stratifications subsurface we observe in the Doppler images. Those stratification surface features are very different, with very different lifetimes and very different rotational behaviors. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>and with sunspots the size of earth comming and going with periods of days. </DIV></p><p>These too are very easily linked to intense atmospheric discharges in the solar atmosphere. If you overlay an 171A image on top of a sunspot image, you will always find a significant area of discharges occuring directly around the sunspot. The sunspot is nothing more than an atmospheric "hole" in a particular plasma layer, much like an eye of a tornado. It allows us to see deeper into the solar atmosphere, to another layer below the photosphere. The atmospheric events from the intense electrical discharges cause tornado like formations to occur in the solar atmosphere. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>The vast and changing magnetic fields also indicate a large amount of moving material. </DIV></p><p>Those vast and changing magnetic fields aree directly related to the vast and changing current flows in the solar atmosphere. As the electrical discharge pattern changes, so do the magnetic field lines. That is why they are so dynamic and change so quickly.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Throw in the fact that there is no way that iron and other metals remain solid at the energy densities present on the sun, especially below the surface, and the concept becomes absurd.</DIV></p><p>You missed an important issue here. The outer most layers of the sun's atmosphere are demonstratably hotter than the layers underneath. The corona temps reach millions of degrees, whereas the chromosphere ranges from around 6K where it meets up with the photosphere to about 20K at the border of the corona. Sunspot activity is typically asocated with *lower* termperatures than we see at the photophere because there are cooler layers under the photopshere. There is a silicon plasma layer under the photosphere that is much cooler than the surface of the photosphere. Likewise, as we decend into the solar atmosphere, the temperatures are cooler and the plasma is more dense. The temperatures at the stratification subsurface are closer to 1200K than 6000K. If there were no heat separation occuring in the solar atmosphere, your logic would be applicable and sound. As it is however, you've made assumptions about the heat distribuition that are easily show to be incorrect. If the heat source were purely internally driven your logic would be sound and reasonable, but then the atmospheric acttivity is not internally powered. </p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>So, do you really want me to go into details on how spectroscopy is done?</DIV></p><p>No, I want you to go into details on how you know that the sun is not mass separted to any great degree. I will grant you that *if* we *assumed* that it was not mass separted very much, then your method of calculating elementatal abundance numbers from spectroscopy would be accurate. It's your *assumption* that I believe is incorrect, not the spectroscopy data.</p><p>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>Because the spectra does show the presence of iron, nickel, magnesium, calcium, silicon, etc in the photosphere....but the numbers are dwarfed by the amount of hydrogen and helium. <br /> Posted by Saiph</DIV></p><p>The "dwarf" part here is related to the total number of photons emitted and the total absorbtion spectrum. The reason that iron and nickel ions are less common is that they only occur during electical discharge events whereas the hydrogen corona, and helium chromosphere are the hotttest two layers and emit the most photons since they emit them from the entire layer of the sun. The fact they are located in the upper atmosphere measn that they absorb and block more photons that other sorts of elements. There is a logical reason why a Birkeland solar model would anticiipate a spectrum that was heavily skewed to hydrogen and helium since these elements emit and absorb the most photons. Counting photons can't tell the composition in a mass separated solar model. That method will only work *if the sun is not mass separated to any signficiant percentage". You'll need to explain to me how come iron and nickel would stay mixed with light elements like hydrogen and helium with that stratification subsurface sitting in the middle of your convection zone. You might also take a look a coronal rain to figure out how you intend to explain that phyenomenon in a non mass separated atmosphere because I'm going to ask you about it, particularly when we start analysing that LMSAL image. </p> <div class="Discussion_UserSignature">
