" 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.
