Consistent Solar Evolution Model Including Diffusion and Radiative Acceleration Effects

The solar evolution has been calculated including all the e ects of the di usion of helium and heavy elements. Monochromatic opacities are used to calculate radiative accelerations and Rosseland opacities at each evolution time step, taking into account the local abundance changes of all important (21) chemical elements. The OPAL monochromatic data are used for the opacities and the radiative accelerations. The Opacity Project data are needed to calculate how chemical species and electrons share the momentum absorbed from the radiation ux.
