Zahn (Rapporteur)In this thesis we have studied different aspects of modelling the solar internal structure. The accuracy of Helioseismology gives strong constraints on the structure of solar models. The best standard models (models where convection and microscopic diffusion are the only transport processes taken into account) reproduce the sound speed of the seismic Sun (obtained by inversion of seismic modes) with a deviation smaller than 1%. With such an accuracy we tested the effects on the models of variations in the quantities used for their calibration, ...
