We report on a new determination of the iron abundance of HE 0107-5240, based on the detection of two Fe II lines in an UV spectrum of the star, which yields [Fe/H]=-5.7. Another interesting metal-poor star recently discovered with Hamburg/ESO Survey (HES) is HE 0557-4840. With [Fe/H]=-4.8, it is the first star located in the "gap" in the metallicity distribution function of the galactic halo, in metallicity between the two stars known at [Fe/H]>-4.0. HE 0557-4840 is carbon-enhanced (i.e.,...[Show more]
