High Resolution Spectroscopy of Two Anomalous Groups in M67
Abstract
We present results concerning two anomalous sub-groups of near-turnoff stars in M67, blue stragglers and bright subgiants. Observations were conducted using the WIYN 3.5 m telescope in conjunction with the HYDRA spectrograph at Kitt Peak National Observatory. We include a low precision radial velocity survey and the preliminary results of an abundance study which may lead to new insights into the evolution of such objects. Support for this was provided by NSF grant AST 09-08342.
