    The shape of oxygen abundance profiles explored with MUSE: evidence for widespread deviations from single gradients
    We characterised the oxygen abundance radial distribution of a sample of 102 spiral galaxies observed with VLT/MUSE using the O3N2 calibrator. The high spatial...

    The single-sided pulsator CO Camelopardalis
    CO Cam (TIC 160268882) is the second 'single-sided pulsator' to be discovered. These are stars where one hemisphere pulsates with a significantly higher...
