Insights in Binary Evolution from Open Cluster Stellar Populations

Observations of star cluster populations were instrumental in developing the theory of single-star stellar evolution, and star clusters can still provide many important observational constraints when it comes to understanding stellar evolution in binary systems. Stars in binary systems will often interact through tidal forces, evolve through Roche lobe overflow and mass transfer, or even merge together at some point in their evolution. Models of these  binary interaction processes remain uncertain, making the evolutionary paths of binaries difficult to predict. I will discuss some of the techniques used to identify post-mass-transfer binaries in open clusters. Many of the post-mass-transfer binaries we find with these techniques have characteristics at odds with expectations from standard binary evolution models, and I will review some of the insights these detections provide about binary evolution pathways.
