INFLUENCE OF HEAVY ELEMENT AND ROTATIONALLY INDUCED DIFFUSIONS ON THESOLAR MODELS

We present the results of solar model computation done with the latest Livermore opacities. Models without diffusion, with hydrogen diffusio n only and with hydrogen and heavy elements diffusion are considered. The influence of mixing below the convective envelope induced by rotat ion and angular momentum losses is also discussed. The sound speed of our best model, does not deviate from that of Basu's seismic one by mo re than about 10(-3); p-mode frequencies are also compared with observ ations and frequencies for low order p and g-modes are given.
