    A search for magnetic fields on central stars in planetary nebulae
    Context. One of the possible mechanisms responsible for the panoply of shapes in planetary nebulae is the presence of magnetic fields that drive the ejection of...

    A search for photometric variability towards M71 with the Near-Infrared Transiting ExoplanetS Telescope
    We present the results of a high-cadence photometric survey of an 11 arcmin × 11 arcmin field centred on the globular cluster M71, with the Near-Infrared...

    A search for red giant solar-like oscillations in all Kepler data
    The recently published Kepler mission Data Release 25 (DR25) reported on ˜197 000 targets observed during the mission. Despite this, no wide search for red...

    A search for transiting planets around hot subdwarfs. I. Methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS
    Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent...
