Population Synthesis in Globular Clusters
Abstract
We are endeavoring to characterize the luminosity function of the lower main sequence of simple stellar populations. We have examined seven clusters in the Large Magellanic Cloud in two optical wavelengths and have produced color-magnitude diagrams and luminosity functions for the brightest resolved stars. We also have the total light from those same regions in each cluster. Based on the ratio of resolved light from individual stars to the integrated cluster flux and considering constraints of current stellar evolution models, we have created models of the cluster luminosity functions beyond the crowding and confusion limit. We will present limits on the slope of the main sequence luminosity function and illustrate the universality of slopes of the luminosity functions at advance stages of stellar evolution.
