    A study of the capabilities for inferring atmospheric information from high-spatial-resolution simulations
    In this work, we study the accuracy that can be achieved when inferring the atmospheric information from realistic numerical magneto-hydrodynamic simulations...

    A study of the effect of rotational mixing on massive stars evolution: surface abundances of Galactic O7-8 giant stars
    Context. Massive star evolution remains only partly constrained. In particular, the exact role of rotation has been questioned by puzzling properties of OB...

    A study of the interplay between ionized gas and star clusters in the central region of NGC 5253 with 2D spectroscopy
    Context. Starbursts are one of the main contributors to the chemical enrichment of the interstellar medium. However, mechanisms governing the interaction...

    A study of the neglected Galactic H ii region NGC 2579 and its companion ESO 370-9
    Context: The Galactic H ii region NGC 2579 has stayed undeservedly unexplored due to identification problems which persisted until recently. Both NGC 2579 and...

    A sub-Earth-mass planet orbiting Barnard's star
    Context. ESPRESSO guaranteed time observations (GTOs) at the 8.2m VLT telescope were performed to look for Earth-like exoplanets in the habitable zone of nearby...

    A sub-Neptune and a non-transiting Neptune-mass companion unveiled by ESPRESSO around the bright late-F dwarf HD 5278 (TOI-130)
    Context. Transiting sub-Neptune-type planets, with radii approximately between 2 and 4 R ⊕, are of particular interest as their study allows us to gain insight...
  • Publication
    A substellar component orbiting the F-star 30 Arietis B
    Context: Most current radial velocity planet search programs have concentrated on stars of one solar mass. Our knowledge on the frequency of giant planets and...

    A substellar mass function for Alpha Persei
    We present a deep, wide-field optical survey of the young stellar cluster Alpha Per, in which we have discovered a large population of candidate brown dwarfs...
  • Publication
    A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096
    Context. Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes...
