Y 2 Isochrones with an Improved Core Overshoot Treatment

Year: 2004

Type: article

Abstract: Convective core overshoot affects stellar evolution rates and the dating of stellar populations. In this paper, we provide a patch to the Y 2 isochrones with an improved treatment of convective core overshoot. The new tracks cover the transition mass range from no convective core to a fully developed convective core. We compare the improved isochrones to CMDs of a few well-observed open star clusters in the Galaxy and the Large Magellanic Cloud. Finally, we discuss future prospects for improving the treatment of core overshoot with the help of asteroseismology.
