You observe a binary star system that consists of two nearly identical main-sequence stars, but you cannot resolve the binary (so it looks like a single star).Where would this "star" fall on the H-R diagram relative to the position of only a single star? If a star cluster consisted entirely of near-identical binary star systems such as these, what effect would this have on estimating the cluster's age?
