The billion-year-old clusters of the Magellanic Clouds
Five clusters of the Magellanic Clouds in the age range of about one billion years have faint enough photometry to allow comparison with theoretical models. Semiempirical relationships are derived from various theoretical models that allow a determination of ages and chemical abundances for the clus...

description | Five clusters of the Magellanic Clouds in the age range of about one billion years have faint enough photometry to allow comparison with theoretical models. Semiempirical relationships are derived from various theoretical models that allow a determination of ages and chemical abundances for the clusters in question. Values for (Fe/H) ranging from -0.8 to -1.3 are found, and ages range from 0.7 to 1.1 billion years. |
