Interview with Anna Frebel by Gerhard Huber
This star, SM0313, formed within the second generation of stars in the universe, soon after the very first stars exploded. We determined its chemical abundances of this stars to find out from what kind of gas cloud this object formed. The abundances are so low that only one first star could have provided the elements to the cloud when it exploded as one of the first ever massive supernova.
Using the stellar chemical abundances is the best and most exciting way to reconstruct the nature and properties of the short-lived elusive first stars and their explosions.

"A single low-energy, iron-poor supernova as the source of metals in the star SMSSJ031300.36-670839.3" by Keller, Bessell, Frebel, et al. 2014, published in Nature 507 (Febuary 13 issue). This is work done by MIT astronomers Anna Frebel and Dr. Heather Jacobson in collaboration with astronomers around Stefan Keller from Mt. Stromlo Observatory of the Australian National University in Canberra, Australia.
