| Abstract: |
During the last decade we have seen a remarkable interplay of theory and observations, leading to many successes in helioseismology and the understanding of the evolution of young stars. Future developments, especially large parallax surveys, will permit us to investigate many other types of stars with equal accuracy. After a review of the sensitivity of stellar models to assumed chemical composition, I show that models which work near the solar abundance currently fail at lower metallicity. I argue that new parallax surveys aid model calibration only if we also have highly accurate temperatures and metallicities over wide swaths of the H-R diagram. |
