Accurate Metallicities for Very Metal-poor Stars from the Ca ii Infrared Triplet
The Ca ii H and K lines are among the few features available to infer the metallicity of extremely metal-poor stars from medium-resolution spectroscopy. Unfortunately, these lines can overlap with absorption produced in the intervening interstellar medium, introducing systematic errors in the derive...
