| Description | A solar model which includes the plausible presence of a mild mixing in the solar inner radiative zone is presented. The mixing is supposed to result from the hydrodynamical instabilities which may occur in a differentially rotating medium leading then to turbulent diffusion. The model includes up-to-date input physics and takes into account the inhibition of the turbulent motions, due to molecular weight gradients (i.e. for $M_{r}/M_{⊙}$ < 0.5). The properties of the model are compared to the standard model properties and to observational results: this turbulent diffusion mixing (TDM) improves the results on surface abundances of the light elements $(^{7}$Li,$ ^{3}$He) and does not reduce the solar neutrino flux relative to the standard model. Moreover preliminary results show that this TDM weakly modifies the oscillation frequencies. |
