Solar Neutrinos and the Primordial Sun

W.C. Haxton.


I discuss the possibility that the large-scale segregation of metals that accompanied planet formation might have left an imprint on the composition of the primordial Sun. Motivated in part by recent Borexino measurements of CN solar neutrinos, I stress how the additional linear metallicity dependence of this flux could be exploited to constrain the composition of the solar core. The gas in the core is arguably the earliest preserved sample of the material out of which our solar system formed.
