    The pristine nature of SMSS 1605−1443 revealed by ESPRESSO
    Context. SMSS J160540.18−144323.1 is the carbon-enhanced metal-poor (CEMP) star with the lowest iron abundance ever measured, [Fe/H] = −6.2, which was first...

    The Pristine survey - I. Mining the Galaxy for the most metal-poor stars
    We present the Pristine survey, a new narrow-band photometric survey focused on the metallicity-sensitive Ca H&K lines and conducted in the Northern hemisphere...
  • Publication
    The Pristine survey - III. Spectroscopic confirmation of an efficient search for extremely metal-poor stars
    The Pristine survey is a narrow-band, photometric survey focused around the wavelength region of the Ca II H&K absorption lines, designed to efficiently search...

    The Pristine survey - V. A bright star sample observed with SOPHIE
    With the aim of probing the properties of the bright end of the Pristine survey and its effectiveness in selecting metal-poor stars, we selected a sample of...
  • Publication
    The Pristine survey - VI. The first three years of medium-resolution follow-up spectroscopy of Pristine EMP star candidates
    We present the results of a 3-yr long, medium-resolution spectroscopic campaign aimed at identifying very metal-poor stars from candidates selected with the...
  • Publication
    The Pristine survey - VII. A cleaner view of the Galactic outer halo using blue horizontal branch stars
    We use the Pristine survey CaHK narrow-band photometry, combined with the Sloan Digital Sky Survey (SDSS)ugr photometry, to provide a cleaner sample of blue...
  • Publication
    The Pristine Survey - VIII. The metallicity distribution function of the Milky Way halo down to the extremely metal-poor regime
    The Pristine survey uses narrow-band photometry to derive precise metallicities down to the extremely metal-poor regime ( [Fe/H] < -3), and currently consists...
  • Publication
    The Pristine survey - X. A large population of low-metallicity stars permeates the Galactic disc
    The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that...
