Probing the radiative zones of stars: Present status and developments
CEA/IRFU/Service d'Astrophysique, CE Saclay, 91191 Gif-sur-Yvette Cedex, France
Seismology of Sun and stars associated to precise solar neutrino detections reveals microscopic and macroscopic behaviors of radiative zones that were not anticipated by stellar modeling predictions. These results allow us to check the hypotheses of the equations used in stellar evolution for long. In this review, I list some of the problems which emerge from these confrontations both on the description of the Sun or solar-like stars and on the envelopes of intermediate-type stars, then I summarize the cases at least partly solved in using 3D MHD simulations, new opacity calculations and laboratory experiments. This review shows also how we hope to progress on the others inside our OPAC consortium or in using the coming detection of neutrino fluxes.
