Integrated UV colors and cluster distances.
Abstract
Population synthesis models of star clusters predict a correlation between the V magnitude of core He-burning stars and the integrated UV color (15-31) of their parent stellar cluster. Available observations disclose a substantial agreement with these theoretical evaluations. The existence of this relationship suggests a method to infer information about distance modulus of distant young stellar clusters.
