III. Conclusions, Related Observations, and Remaining Problems
Historical Info Evidence Conclusions
The solar neutrino flux has been a long-standing puzzle  for the H-filled Sun. The above observations confirm that it is now obsolete. On the other hand, a Fe-rich Sun from SN debris offers a direct explanation for these observations and for a) heterogeneous accretion of terrestrial planets [2-4], b) primordial He and radiogenic Xe-129 retained inside the Earth today [5,6] c) non-magmatic iron meteorites [7, pp. 385-406**], d) isotopic anomalies and decay products of short-lived nuclides in iron [pp. 385-406] as well as in primitive [** See pp361-384] meteorites , e) the iron gradient in planets and in the planetary system [pp. 608-611], and a) experimental affirmation  of all three tests originally proposed for mass fractionation in the Sun .
Two of three major objections to the Fe-Sun have been resolved and a third is in progress. The discovery [11,12] of pulsar planets confirmed that planetary systems can form directly from SN debris . The Hubble telescope verified the existence of axial ejections from SNs [pp. 241-249]. Extrapolations of trends from the cradle of the nuclides book cover  indicate an inherent instability in assemblages of neutrons that may explain solar luminosity and the solar neutrino flux [14,15]. After correcting for fractionation, solar abundances generally correlate with nuclear stability , as Harkins had predicted , except for a large excess of H-1. This anomalous H-1 and the outflow of H+ ions in the solar wind may be by-products of solar luminosity [14,15,17-19]
