    The Present and Future of Planetary Nebula Research. A White Paper by the IAU Planetary Nebula Working Group
    We present a summary of current research on planetary nebulae and their central stars, and related subjects such as atomic processes in ionized nebulae, AGB and...

    The Pristine dwarf galaxy survey - IV. Probing the outskirts of the dwarf galaxy Boötes I
    We present a new spectroscopic study of the dwarf galaxy Boötes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together...

    The Pristine dwarf galaxy survey-V. The edges of the dwarf galaxy Hercules
    We present a new spectroscopic study of 175 stars in the vicinity of the dwarf galaxy Hercules (d ~ 132 kpc) with data from the Anglo-Australian Telescope and...

    The Pristine Inner Galaxy Survey (PIGS) VII: a discovery of the first inner Galaxy CEMP-r/s star
    Well-studied very metal-poor (VMP, [Fe/H] <-2) stars in the inner Galaxy are few in number, and they are of special interest because they are expected to be...

    The Pristine survey - XIX. Cu and Zn abundances in metal-poor giants
    Metal-poor stars formed from a gas enriched by the ejecta of the explosion of one/few generations of first massive stars. With the Pristine photometry combined...
  • Publication
    The Pristine survey - XVI. The metallicity of 26 stellar streams around the Milky Way detected with the STREAMFINDER in Gaia EDR3
    We use the photometric metallicities provided by the panoramic Pristine survey to study the veracity and derive the metallicities of the numerous stellar...
  • Publication
    The Pristine survey - XVII. The C-19 stream is dynamically hot and more extended than previously thought
    The C-19 stream is the most metal-poor stellar system ever discovered, with a mean metallicity [Fe/H] = -3.38 ± 0.06. Its low metallicity dispersion (σ [Fe/H] <...

    The Pristine survey - XVIII. C-19: tidal debris of a dark matter-dominated globular cluster?
    The recently discovered C-19 stellar stream is a collection of kinematically associated metal-poor stars in the halo of the Milky Way lacking an obvious...

    The Pristine survey XIII: uncovering the very metal-poor tail of the thin disc
    We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre spanning a wide range of metallicities from the...
