TL;DR: In this paper, the authors compare the helioseismic properties of two solar models, one calibrated with the OPAL opacities and the other with the recent Los Alamos LEDCOP (Light Element Detailed Configuration Opacity) opACities.

TL;DR: In this article, the effects of the Grevesse & Sauval solar mixture and the European Nuclear Astrophysics Compilation of Reaction Rates (NACRE) nuclear reaction rates on the calculated neutrino fluxes and the p-mode oscillation spectrum of calibrated standard solar models were examined.

TL;DR: In this article, the authors explore the potential for mixed core models to solve the neutrino problem and compare the structure, neutrinos flux, and oscillation frequency predictions for several models in which the inner 25% of the radius is homogenized, taking into account the effects of non-local equilibrium abundances of 3He.

Abstract: We propose a pulsation driving mechanism for {gamma} Doradus variable stars. This mechanism requires that the local convective timescale at the base of the envelope convection zone be comparable to or longer than the pulsation period. This mechanism explains both the red and blue edges of the {gamma} Dor instability strip. We predict that some cadidate {gamma} Dor stars summarized by Handler (1999) may actually be too hot or too cool to be {gamma} Dor variables.

TL;DR: In this paper, the authors compare the observed and calculated sound speed profile and oscillation frequencies of solar models calibrated using the new Los Alamos LEDCOP and Livermore OPAL mean opacities for the same element mixture.
