The lowest detected stellar Fe abundance: the halo star SMSS J160540.18−144323.1

We report the discovery of SMSS J160540.18−144323.1, a new ultra metal-poor halo star discovered with the SkyMapper telescope. We measure Fe/H = -6.2 ± 0.2 (1D LTE), the lowest ever detected abundance of iron in a star. The star is strongly carbon-enhanced, C/Fe = 3.9 ± 0.2$, while other abundances...
