    Complex K: Supernova Origin of Anomalous-velocity H I Structure
    We address one of the lingering mysteries of high-velocity clouds: If the anomalous negative velocities are the result of the approaching gas from old...
  • Publication
    Comprehensive comparison between APOGEE and LAMOST. Radial velocities and atmospheric stellar parameters
    Context. In the era of massive spectroscopy surveys, automated stellar parameter pipelines and their validation are extremely important for an efficient...

    Conducting the SONG: The Robotic Nature and Efficiency of a Fully Automated Telescope
    We present a description of “the Conductor,” an automated software package that handles all observations at the first Stellar Observations Network Group (SONG)...
  • Publication
    Confirmation of the link between central star binarity and extreme abundance discrepancy factors in planetary nebulae
    It has recently been noted that there seems to be a strong correlation between planetary nebulae with close binary central stars and highly enhanced...
  • Publication
    Constraining gas metal mixing strength in simulations using observations of the Milky Way's disc
    This work explores the mixing rate of metals in the interstellar medium (ISM), comparing observational constraints from our solar neighbourhood to high...
  • Publication
    Constraining Metallicity-dependent Mixing and Extra Mixing Using [C/N] in Alpha-rich Field Giants
    Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several...
  • Publication
    Constraining stellar and orbital co-evolution through ensemble seismology of solar-like oscillators in binary systems. A census of oscillating red giants and dwarf stars in Gaia DR3 binaries
    Context. Binary systems constitute a valuable astrophysics tool for testing our understanding of stellar structure and evolution. Systems containing at least...
  • Publication
    Constraining the Epoch of Reionization from the Observed Properties of the High-z Universe
    We combine observational data on a dozen independent cosmic properties at high-z with the information on reionization drawn from the spectra of distant luminous...
  • Publication
    Constraining the overcontact phase in massive binary evolution. II. Period stability of known O+O overcontact systems
    Context. Given that mergers are often invoked to explain many exotic phenomena in massive star evolution, understanding the evolutionary phase directly...
