The Most Metal-Poor Stars. I. Discovery, Data, and Atmospheric Parameters

We report the discovery of 34 stars in the Hamburg/ESO Survey for metal-poor stars and the Sloan Digital Sky Survey that have [Fe/H] [< over ~]–3.0. Their median and minimum abundances are [Fe/H] = –3.1 and –4.1, respectively, while 10 stars have [Fe/H] < –3.5. High-resolution, high signal-to-...
