An age difference of two billion years between a metal-rich and a metal-poor globular cluster
- Volume 8, Issue 31 - article #15
- An absolute age of about ten billion years is determined for the globular cluster 47 Tucanae, which is about two billion years younger than the cluster NGC 6397 is thought to be, suggesting that metal-rich clusters like 47 Tucanae formed later than metal-poor clusters like NGC 6397.

An absence of ex-companion stars in the type Ia supernova remnant SNR 0509−67.5
- Volume 7, Issue 11 - article #16
- The central region of the supernova remnant SNR 0509−67.5 in the Large Magellanic Cloud is shown to contain no ex-companion star, which suggests it was formed by an explosion resulting from the merger of two white dwarf stars.
