Blue straggler stars: Lessons from open clusters

  title={Blue straggler stars: Lessons from open clusters},
  author={Aaron Matthew Geller},
Open clusters enable a deep dive into blue straggler characteristics. Recent work shows that the binary properties (frequency, orbital elements and companion masses and evolutionary states) of the blue stragglers are the most important diagnostic for determining their origins. To date the multi-epoch radial-velocity observations necessary for characterizing these blue straggler binaries have only been carried out in open clusters. In this paper, I highlight recent results in the open clusters… CONTINUE READING
