WIYN Open Cluster Study XXXII: Stellar Radial Velocities in the Old Open Cluster NGC 188
Aaron M. Geller, Robert D. Mathieu, Hugh C. Harris +1
(Abridged) We present the results of our ongoing radial-velocity (RV) survey of the old (7 Gyr) open cluster NGC 188. Our WIYN 3.5m data set spans a time baseline of 11 years, a ma…
Spectroscopic Abundances in the Open Cluster, NGC 6819
Donald B. Lee-Brown, Barbara J. Anthony-Twarog, Constantine P. Deliyannis +2
High-dispersion spectra of 333 stars in the open cluster NGC 6819, obtained using the HYDRA spectrograph on the WIYN 3.5m telescope, have been analyzed to determine the abundances…
Light-Element Abundances of Giant Stars in the Globular Cluster M71 (NGC 6838)
Maria J. Cordero, Catherine A. Pilachowski, Christian I. Johnson +1
Aluminum is the heaviest light element displaying large star--to--star variations in Galactic globular clusters (GCs). This element may provide additional insight into the origin o…
