    A universal method for solar filament detection from Hα observations using semi-supervised deep learning
    Filaments are omnipresent features in the solar atmosphere. Their location, properties, and time evolution can provide important information about changes in...

    A Very Small Array search for the extended Sunyaev-Zel'dovich effect in the Corona Borealis supercluster
    We present interferometric imaging at 33 GHz of the Corona Borealis supercluster, using the extended configuration of the Very Small Array. A total area of 24...
  • Publication
    A VLT/FORS2 spectroscopic survey of individual stars in a transforming dwarf galaxy
    Understanding the properties of dwarf galaxies is important not only to put them in their proper cosmological context, but also to understand the formation and...

    A warm super-Neptune around the G-dwarf star TOI-1710 revealed with TESS, SOPHIE, and HARPS-N
    We report the discovery and characterization of the transiting extrasolar planet TOI-1710 b. It was first identified as a promising candidate by the Transiting...

    A wide deep infrared look at the Pleiades with UKIDSS: new constraints on the substellar binary fraction and the low-mass initial mass function
    We present the results of a deep wide-field near-infrared survey of 12 deg2 of the Pleiades conducted as part of the United Kingdom Infrared Telescope (UKIRT)...
  • Publication
    A wide-area view of the Phoenix dwarf galaxy from Very Large Telescope/FORS imaging
    We present results from a wide-area photometric survey of the Phoenix dwarf galaxy, one of the rare dwarf irregular/dwarf spheroidal transition-type galaxies...
  • Publication
    A young binary brown dwarf in the R-CrA star formation region
    We present imaging and spectroscopic observations with HST (WFPC2, ACS/HRC and STIS), VLT (FORS2) and Keck (HIRES) of the dM 8 ultra-cool dwarf DENIS-P J185950...
  • Publication
    A young spectroscopic binary in a quintuple system part of the Local Association
    Context. Double-lined spectroscopic (SB2) binaries allow us to obtain a direct determination of the masses of their components, which is essential to test...
  • Publication
    Absolute dimensions and apsidal motion of the eclipsing binaries V889 Aquilae and V402 Lacertae
    Context. Double-lined eclipsing binaries allow the direct determination of masses and radii, which are key for testing stellar models. With the launch of the...
