ニュートリノ•日震学•太陽モデル

抄録

There has been a long-standing discrepancy between the number of neutrinos expected from the sun and the number we actually detect. One possible way to account for this is that our theoretical solar model is inaccurate. However, recent progress in helioseismology has shown that the real sun is very close to the latest solar models. On the other hand, very recent experiments of neutrino detection provided us evidence for neutrino oscillation. I discuss what we should do and what we can do in this situation for the neutrino physics from the astrophysical side.
