Abstract
We present the results of a quantitative study of the degree of extension to the boundary of the classical convective core within intermediate-mass stars. The basis of our empirical study is the stellar population of four young populous clusters in the Magellanic Clouds that has recently been detailed by Keller, Bessell, & Da Costa. The sample affords a meaningful comparison with theoretical scenarios with varying degrees of convective core overshoot and binary star fraction. Two critical properties of the population, the main-sequence luminosity function and the number of evolved stars, formthe basis of our comparison between the observed data set and that simulated from the stellar evolutionary models. On the basis of this comparison weconclude that the case of no convective core overshoot is excluded at a 2 sigma level.
