    A numerical study of interactions and stellar bars
    For several decades, it has been known that stellar bars in disc galaxies can be triggered by interactions, or by internal processes such as dynamical...

    A pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 characterized with CHEOPS
    We report the discovery and characterization of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in the...
  • Publication
    A PCA approach to stellar effective temperatures
    Context. The derivation of the effective temperature of a star is a critical first step in a detailed spectroscopic analysis. Spectroscopic methods suffer from...

    A peculiar galaxy appears at redshift 11: properties of a moderate-redshift interloper
    In 2011 Laporte et al. reported a very high redshift galaxy candidate: a lensed J-band dropout (A2667-J1). J1 has a photometric redshift of z= 9.6-12, the...
  • Publication
    A peculiar Of star in the Local Group galaxy IC 1613
    Context. Results from the theory of radiatively driven winds are nowadays incorporated in stellar evolutionary and population synthesis models, and are used in...

    A peculiar stellar complex in NGC 6946 or the blue compact galaxy in front of this galaxy?
    The origin of the peculiar stellar complex in the outskirts of the spiral galaxy NGC 6946 is discussed. The complex hosts a superstar cluster, two dozen smaller...
