Thank you for the link Oliver. You are obviously in a number of discussions regarding this theory, and that helps to explain why you have a penchant for repeating yourself!
Current solar theories are based on modelling, where the result of the model must meet the current solar levels of luminosity, output and size. Has your theory been modelled, and if so, how well does the model meet the above criterion?
Regarding the solid inner body rotation found through mapping of the solar interior by helioseismology, it is suggested that the solid rotating inner body is a neutron star (your theory) or a rocky oceon (ala Peter Blachle), however it also seems that an explanation would relate to the formation of metallic hydrogen, similar to what has occurred in the lower atmosphere of Jupiter. Certainly at the range of depths mentioned for this body (roughly 1/3 to 1/5 of the solar radius below the observable surface) there is enough mass and pressure to metallisize the hydrogen.
I have done alot of reading regarding this premise but I have yet to see an answer to my questions regarding the new findings from seismic measurements by Romanowicz et al. You state that your measurements support the premise that the lower mantle is unmelted and undifferentiated, and you rely on the amount of primordial Iodine 129 and Plutonium 244 released during the intial phase of the planets formation as the basis for this premise.
The new measurements of s-wave and p-wave propagation through the lower mantle have identified so called "superplumes", regions where heated magma rising from the lower mantle contact and spread at the lithosphere, then cool and sink. It seems clear that there is active mantle recycling from the lower to the upper mantle, which would seem to suggest that the I-129 and Pu-244 from the lower mantle region must have escaped, or is escaping.
This would seem to require an explanation from you regarding the measurements you have made. Specifically, how do your measurements explain the mantle recycling?
