The metal-poor end of the Spite plateau. II. Detailed chemical
  investigation
  Context. The study of old, metal-poor stars deepens our knowledge on the
early stages of the universe. In particular, the study of these stars gives us
a valuable insight into the masses of the first massive stars and their
emission of ionising photons. Aims. We present a detailed chemical analysis and
determination of the kinematic and orbital properties of a sample of 11 dwarf
stars. These are metal-poor stars, and a few of them present a low lithium
content. We inspected whether the other elements also present anomalies.
Methods. We analysed the high-resolution UVES spectra of a few metal-poor stars
using the Turbospectrum code to synthesise spectral lines profiles. This
allowed us to derive a detailed chemical analysis of Fe,
