Description
The detection of solar neutrinos is evidence for ongoing fusion in the core of the sun and neutrinos can still serve as a probe for the solar core. Neutrinos from rare Boron 8 decays are very sensitive to the solar core temperature and their adiabatic flavor conversion depends on the local solar electron density. Solar core size upper bound and solar core temperature and density limits based on Super-Kamiokande I-IV solar neutrino data are presented. Analysis results are shown for B16 Standard Solar Model and K2-A09-12 spin down of solar mass protostar model.
