The stability of solar gravity-mode oscillations and the structure of the sun

The g-mode oscillations stability for the interior of solar models with low heavy-element abundances and models with turbulent diffusion mixing inside is investigated by a quasi-adiabatic approximation. The models with low Z are found to be most unstable. It is pointed out that only the models with low Z are in agreement with the solar neutrino experiment and the observed solar gravity mode oscillations.
