    Seismology of delta Scuti stars in the Praesepe cluster. II. Identification of radial modes and their associated stellar parameters
    An analysis based on a comparison between observations and stellar models has been carried out to identify radial modes of oscillations in several multi...

    Self-supervised component separation for the extragalactic submillimetre sky
    We use a new approach based on self-supervised deep learning networks originally applied to transparency separation in order to simultaneously extract the...

    Sensitivity of helioseismic gravity modes to the dynamics of the solar core
    Context: The dynamics of the solar core cannot be properly constrained through the analysis of acoustic oscillation modes. Gravity modes (g modes) are necessary...

    Separation between RR Lyrae and type II Cepheids and their importance for a distance determination: the case of omega Cen
    The separation between RR Lyrae (RRLs) and type II Cepheid (T2Cs) variables based on their period is debated. Both types of variable stars are distance...

    Shape and spin determination of Barbarian asteroids
    Context. The so-called Barbarian asteroids share peculiar, but common polarimetric properties, probably related to both their shape and composition. They are...
