A team of international astronomers has discovered a low-mass star that exhibits the peculiar chemical abundance ratios associated with the process of creating new atomic nuclei (nucleosynthesis) in a first-generation very-massive star. The team, which includes Timothy Beers, the Notre Dame Chair in Astrophysics at the University of Notre Dame, used the 8.2 m Subaru Telescope’s High Dispersion Spectrograph to make the discovery. The team members published a report, “A chemical signature of first-generation very-massive stars,” in the Aug. 22 issue of the journal Science.
