    Two's a crowd? Characterising the effect of photometric contamination on the extraction of the global asteroseismic parameter νmax in red-giant binaries
    Context. Theoretical scaling relations for solar-like oscillators and red giants are widely used to estimate fundamental stellar parameters. The accuracy and...

    Unusual high-frequency oscillations in the Kepler δ Scuti star KIC 4840675
    We show that the star KIC 4840675 observed by Kepler is composed of three stars with a rapidly rotating A-type star and two solar-type fainter companions. The A...

    Weighing stars from birth to death: mass determination methods across the HRD
    The mass of a star is the most fundamental parameter for its structure, evolution, and final fate. It is particularly important for any kind of stellar...

    Young [α/Fe]-enhanced stars discovered by CoRoT and APOGEE: What is their origin?
    We report the discovery of a group of apparently young CoRoT red-giant stars exhibiting enhanced [α/Fe] abundance ratios (as determined from APOGEE spectra)...
