    Ultracool dwarf benchmarks with Gaia primaries
    We explore the potential of Gaia for the field of benchmark ultracool/brown dwarf companions, and present the results of an initial search for metal-rich/metal...

    Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
    We examine the spatial clustering of blue horizontal branch (BHB) stars from the u-band of the Canada-France Imaging Survey (CFIS, a component of the...

    Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
    Accurate distances to individual Milky Way stars provided by Gaia have allowed us to derive stellar age distributions from colour─magnitude diagrams (CMD)...

    Uncovering the birth of the Milky Way through accurate stellar ages with Gaia
    Knowledge of the ages of the stars formed over a galaxy's lifetime is fundamental to an understanding of its formation and evolution. However, stellar ages are...

    Understanding the evolution and dust formation of carbon stars in the Large Magellanic Cloud via the JWST
    Context. Carbon stars have been, and still are, extensively studied. Given their complex internal structure and their peculiar chemical composition, they are...

    UNIONS: The Ultraviolet Near-infrared Optical Northern Survey
    The Ultraviolet Near-Infrared Optical Northern Survey (UNIONS) is a "collaboration of collaborations" that is using the Canada─France─Hawai'i Telescope, the Pan...

    Unveiling shocks in planetary nebulae
    The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as...

    Unveiling the chemical fingerprint of phosphorus-rich stars. I. In the infrared region of APOGEE-2
    Context The origin of phosphorus, one of the essential elements for life on Earth, is currently unknown. Prevalent models of Galactic chemical evolution (GCE)...

    Unveiling the chemical fingerprint of phosphorus-rich stars: II. Heavy-element abundances from UVES/VLT spectra
    Context. The atmospheres of phosphorus-rich (P-rich) stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an...
