Baud, I read the site. I also read the cites. Here’s what I think.
It cites 3 scientists extensively - birkeland, bruce, and manuel.
Birkeland was a scientist from the early 1800’s who made his claims based on research done that planetary B-fields (magnetic fields) are results of shifting E-fields. This led to the logic that our own planetary magnetic field was generated from the incongruities in a solid iron core moving within a liquid iron covering, which is then covered by the mantle, crust, atmosphere, etc. Birkeland would further postulate that the sun’s B-field is also generated by a spinning iron core - one that rotates every 23.7 days.
Bruce was a scientist who further researched that B-fields can be generated by the movements within a cloud of charged particles, and is responsible for much of the solar activity in the solar system, at least atmospherically. This would explain why the surface of the sun is actually hotter than the core.
Oliver Manuel is a professor at U-Missouri Rolla who along with his research associate are the sole scientific advocates of an iron core. He is also the same cite but in the form of a cnn article later as "a small group of maverick scientists).
The main theory of Manuel’s iron core model reasons that the sun and our solar system are survivors of an ancient supernova. The exploded star left a core of iron and expelled most of everything else into orbit around it. The reasoning behind this was that Manuel looked lunar samples and asteroid samples, saw that they were of heavy metals which would be found in the core of a large, aging star, and concluded that it was a possibility that our solar system had been the victim of a small supernova, and our sun was pulsing as an abnormally large and bright dwarf.
Furthermore, the research done by oliver addresses the source of the sun’s energy as neutron decay, which then forms helium and hydrogen ions, which may fuse and that compounded with the B-field generation discovered by Bruce, accounts for the energy released by the Sun.
So… what do i think?
I haven’t done any pen and paper work on this, and am unlikely to, but a brief lookover and mental math tells me that the spontaneous decay of an iron core is highly unlikely to produce the energy that the sun does in itself even under intense pressure. I’m also unimpressed by the static imaging of iron deposits in the sun. Nobody is doubting the presence of iron in the sun. Heavy metals do exist. The question is if it composes a significant amount of the core. An image taken at such a distance would have you believe that the entire core was made of iron when they could just be dispersed sparcely throughout.
What i mean by that is, if you have 10 people, and you arrange them uniformly in a circle, you’d have maybe 5 on the perimeter and a few in between, but if you stand reaaaaally far away and look at the group, you would not be able to see through the group of people and conclude it’s a mass of people, when really they’re just dispersed uniformly. That’s a basic problem with image processing, especially on the astronomical level.
So overall, the idea has weak legs, a lack of scientific support. The site itself, surfaceofthesun.com, probably hurts its cause rather than helps it from my viewpoint. And the condescending, yet baseless insults from Baud doesn’t help the cause either.
