The mixing in the solar core and the neutrino fluxes

TL;DR

This paper explores how introducing mixing in the solar core can increase certain neutrino fluxes without conflicting with helioseismic data, impacting future neutrino detection experiments.

Contribution

It demonstrates that core mixing can be incorporated into solar models without violating helioseismic constraints, specifically increasing 13N neutrino fluxes.

Findings

Mixing in the solar core is compatible with helioseismic data.

Core mixing significantly increases 13N neutrino flux.

Other neutrino fluxes remain largely unaffected.

Abstract

It is shown that it is possible to introduce a mixing in the solar model not in a contradiction with the present data of helioseismology. Particularly it is demonstrated that resulted violation in the sound speed profile is within the uncertainties of helioseismic data. The effect of such mixing in a spherical shell in the central zone of the Sun would be the substantial increase of the neutrino flux from 13N while all other neutrino fluxes will stay practically unchanged. The implications for future experiments are discussed.
