    The shady side of Stellar modelling and its grisly impact on Asteroseismology and Galactic Archeology
    Since the second half of last century, stellar evolution theory has allowed to understand the Color Magnitude Diagram of galactic star clusters, so that now we...

    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 short orbital period binary star at the heart of the planetary nebula M 3-1★
    We present the discovery of a 3h5m orbital-period binary star at the heart of the planetary nebula M 3-1 - the shortest period photometrically variable central...

    The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge
    We compare abundance ratio trends in a sample of ∼11,000 Milky Way bulge stars (R GC < 3 kpc) from the Apache Point Observatory Galactic Evolution Experiment...

    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...
