The Most Metal-Poor Stars. IV. The Two Populations With [Fe/H] [< over ~] -3.0

We discuss the carbon-normal and carbon-rich populations of Galactic halo stars having [Fe/H] [< over ~] -3.0, utilizing chemical abundances from high-resolution, high signal-to-noise model-atmosphere analyses. The C-rich population represents ~28% of stars below [Fe/H] = -3.1, with the present C...
