| Abstract: |
We present an up-to-date set of evolutionary calculations of low mass, metal poor stars, in which mass, metallicity and helium content have been varied. Calculations with and without atomic diffusion have been made. They are mainly intended to allow users direct age determinations of individual globular cluster stars, if their stellar parameters (mass, luminosity) are available (e.g. binaries). Fitting formulae to the age-luminosity relations have been derived to facilitate the application. We also discuss uncertainties due to diffusion and to the general level of disagreement between comparable computations available in the literature. |
