The Distribution of Blue Straggler Stars in the Color–Magnitude Diagrams of Old Open Clusters
We examine the blue straggler star (BSS) populations of six old (≥4 Gyr) open clusters: M67, NGC 188, NGC 6791, Berkeley 32, Berkeley 39, and Trumpler 19. We find that 50% of BSSs have color–magnitude diagram locations corresponding to single stars in the final third of their main-sequence lifetimes...
