The good agreement of standard solar models with helioseismology and the combined analysis of the solar neutrino experiments suggest that the solution of the solar neutrino problem is located in particle physics rather than in astrophysics. The most promising solution is neutrino oscillations, which usually are analyzed within the reduced two-flavor scheme, because the solutions found therein reasonably well reproduce the recent data of Super-Kamiokande about the recoil-electron energy spectrum… 
The age of the Sun and the relativistic corrections in the EOS
We show that the inclusion of special relativistic corrections in the revised OPAL and MHD equations of state has a significant impact on the helioseismic determination of the solar age. Models with
Magnus expansion and three-neutrino oscillations in matter
We present a semi-analytical derivation of the survival probability of solar neutrinos in the three generation scheme, based on the Magnus approximation of the evolution operator of a three level
Microscopic diffusion of partly ionized metals in the Sun and metal-poor stars
An improved microscopic diffusion in stars is presented considering in detail the partly ionized stages of metals. Besides, the influence of degenerate electron-gas and of the contribution of
Astrophysical turbulence modeling
The role of turbulence in various astrophysical settings is reviewed and the ubiquitous presence of magnetic fields that are generally produced and maintained by dynamo action are highlighted.
Normal Accidents of Expertise
The concept of knowledge risk is introduced, and used to characterize the risk of failure in systems of knowledge production, which are increasingly becoming tightly coupled.
