    Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
    Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc RGal ≲ 13 kpc, | ZGal| 0.3 kpc), we...

    Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
    In 1981, the idea of a superwind that ends the life of cool giant stars was proposed1. Extreme oxygen-rich giants, OH/IR stars, develop superwinds with the...

    Relativistic baryonic jets from an ultraluminous supersoft X-ray source
    The formation of relativistic jets by an accreting compact object is one of the fundamental mysteries of astrophysics. Although the theory is poorly understood...
