Solar neutrinos and the primordial Sun
W. C. Haxton

TL;DR
This paper explores how measurements of solar neutrinos, particularly CN neutrinos, can reveal the primordial Sun's composition and the early solar system's material, considering the impact of metallicity segregation.
Contribution
It proposes using the metallicity dependence of CN solar neutrino flux to constrain the solar core's composition, linking neutrino data to early solar system material.
Findings
CN neutrino flux depends linearly on metallicity
Potential to constrain primordial solar core composition
Links solar neutrino measurements to early solar system material
Abstract
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.
