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

T. Nordlander, M. S. Bessell, G. S. Da Costa +12

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…

Four Metal-poor Stars in the Sagittarius Dwarf Spheroidal Galaxy

Anirudh Chiti, Anna Frebel

We present the metallicities and carbon abundances of four newly discovered metal-poor stars with $- 2.2 <$ [Fe/H] $< - 1.6$ in the Sagittarius dwarf spheroidal galaxy. These stars…
