520			_aOne of the most important contributions which stellar structure has made for equilibrium configuration is the theory of self gravitating polytrope. In this thesis, we use the standard solar model SSM of bahcall, serenelli, basu (2005) as a basic to developed a solar models in hydrostatic equilibrium expressing the physical structure of a sequence of two zones polytropes associated to the convective and radiative regions, and three zones polytropes associated to the nuclear, the radiative and the convective regions of the solar interior. We show that a composite three zones polytrope is a good representation for SSM
