    A two-component model of the solar photosphere from the inversion of spectral lines
    A two-component model of the solar photosphere is obtained from the inversion of the intensity profiles of 22 Fe I spectral lines for which very accurate atomic...

    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 Virtual Observatory Census to Address Dwarfs Origins (AVOCADO). I. Science goals, sample selection, and analysis tools
    Context. Even though they are by far the most abundant of all galaxy types, the detailed properties of dwarf galaxies are still only poorly characterised -...

    A VLT-ULTRACAM study of the fast optical quasi-periodic oscillations in the polar V834 Centauri
    Quasi-periodic oscillations (QPOs) of a few seconds have been detected in some polars, the synchronised subclass of cataclysmic systems containing a strongly...

    A VLT/VIMOS view of two Planck multiple-cluster systems: Structure and galaxy properties
    We analysed spectroscopic data obtained with VLT/VIMOS for two multiple-cluster systems, PLCKG214.6+36.9 and PLCKG334.8−38.0, discovered by Planck via their...

    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 wiggling filamentary jet at the origin of the blazar multi-wavelength behaviour
    Context. Blazars are beamed active galactic nuclei (AGNs) known for their strong multi-wavelength variability on timescales ranging from years down to minutes...

    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...

    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...
