The metal-poor end of the Spite plateau - I. Stellar parameters, metallicities, and lithium abundances
Context. The primordial nature of the Spite plateau is at odds with the WMAP satellite measurements, implying a primordial Li production at least three times higher than observed. It has also been suggested that A (Li) might exhibit a positive correlation with metallicity below [Fe/H] ~ −2.5. Previous samples studied …
