    A transiting rocky super-Earth and a non-transiting sub-Neptune orbiting the M dwarf TOI-771
    Context. The origin and evolution of the sub-Neptune population is a highly debated topic in the exoplanet community. With the advent of JWST, atmospheric...

    A transmission spectrum of the planet candidate WD 1856+534 b and a lower limit to its mass
    The cool white dwarf WD 1856+534 was found to be transited by a Jupiter-sized object with a mass at or below 14 M Jup. We used the GTC telescope to obtain and...

    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 Virgo Environmental Survey Tracing Ionised Gas Emission (VESTIGE): XVIII. Reconstructing the star formation history of early-type galaxies through the combination of their UV and Hα emission
    We reconstructed the star formation histories of seven massive (M ⋆ ≳ 10 10 M ⊙) early-type galaxies (ETGs) in the Virgo cluster by analysing their spatially...

    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...
