" The new record for the most metal-poor star: HE 1327-2326 with [Fe/H] = -5.4;

Anna Frebel (Mount Stromlo Observatory)


Using the Subaru telescope, we recently discovered HE 1327-2326, a subgiant or dwarf with [Fe/H] = -5.4. It is only the second star with an extremly low metallicity of [Fe/H] < -5.0. We present our abundance analysis of this very peculiar object (non-detection of Li and high Sr abundance) together with models which try to explain the observed abundance pattern. The discovery paper is accepted for publication in 'Nature'. Note to the organizers: This result will be published in Nature soon (which has a press embargo of this result) we wish to ask for careful treatment of the abstract concerning its access to the general media.


Seminars are also held at JAC, CFHT, and IfA.
