Informal Pizza SeminarWhat Can Solar Neutrinos Tell Us About the Solar Radiative Zone?Cliff BurgessMcGillThe original motivation for searching for solar neutrinos was to acquire a direct probe of solar properties deep within the solar interior. Now that the wild ride in which we learned more about neutrinos than the sun is coming to an end, we can again ask what we might learn about solar physics. This talk is meant as a first small step in this direction, where I'll argue that the existence of resonant neutrino oscillations excludes certain kinds of density fluctuations in the solar interior. I'll argue that the kinds of fluctuations which are excluded may arise from magnetic fields in the solar radiative zone (without requiring a neutrino magnetic moment) and so their absence provides an new constraint on the kinds of magnetic fields which can be present there.
