| Abstract: |
Gray model atmospheres are generally considered a reasonable approximation to make upon stars of mass greater than about 0.6 MSolar. Here we show that non-gray atmospheres can significantly affect evolutionary models, with masses up to 0.9 MSolar. The effect of including a non-gray atmosphere is strongest in the pre-main and post-main Sequence. This may have implications for the ages of the oldest globular clusters. |
