    Triple system HD 201433 with a SPB star component seen by BRITE - Constellation: Pulsation, differential rotation, and angular momentum transfer
    Context. Stellar rotation affects the transport of chemical elements and angular momentum and is therefore a key process during stellar evolution, which is...

    Two new SB2 binaries with main sequence B-type pulsators in the Kepler field
    Context. OB stars are important in the chemistry and evolution of the Universe, but the sample of targets that is well understood from an asteroseismological...

    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)...
