The Chemical Properties of Milky Way and M31 Globular Clusters: II. Stellar Population Model Predictions
ASTRONOMICAL JOURNAL, no. 3 (2005): 1412-1427
摘要
We derive ages, metallicities, and abundance ratios ([alpha/Fe]) from the integrated spectra of 23 globular clusters in M31 by employing multivariate fits to two different stellar population models. We also perform a parallel analysis on 21 Galactic globular clusters as a consistency check and in order to facilitate a differential analysi...更多
