Kepler Image-Subtracted Light Curves and Variable Star Catalog of NGC 6819
Melinda Soares-Furtado, Rianna Kuenzi, Rachel Lee McClure +11
Variable stars in open clusters are valuable probes of stellar evolution. They provide precise measurements of stellar properties, constrain cluster ages and distances, and trace t…
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…
WIYN Open Cluster Study. XCVII. An Extended Radial-Velocity Survey and Spectroscopic Binary Orbits in the Open Cluster NGC 188
Ritvik Sai Narayan, Evan Linck, Robert D. Mathieu +1
We present 35 new spectroscopic-binary orbits from our extended radial-velocity (RV) survey of the old ( Gyr) open cluster NGC 188. Using data from the WIYN Open Clust…
