Blue Straggler Stars in Old Open Clusters and the Kraft Break
Evan Linck, Robert D. Mathieu
We measure the projected rotational velocities () of the solar-like blue straggler stars (BSSs) in the old ( Gyr) open clusters M67, NGC 188, and NGC 6791. We find…

The Distribution of Blue Straggler Stars in the Color-Magnitude Diagrams of Old Open Clusters
Evan Linck, Robert D. Mathieu
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…
