A Chemical Abundance Study of 10 Open Clusters Based on WIYN-Hydra Spectroscopy
Chemical Abundance Study Clusters Based WIYN-Hydra Spectroscopy
2011/10/12
We present a detailed chemical abundance study of evolved stars in 10 open clusters based on Hydra multi-object echelle spectra obtained with the WIYN 3.5m telescope. From an analysis of both equivale...
