    V-type candidates and Vesta family asteroids in the Moving Objects VISTA (MOVIS) catalogue
    Context. Basaltic asteroids (spectrally classified as V-types) are believed to be fragments of large differentiated bodies. The majority of them are found in...
  • Publication
    Validation and atmospheric exploration of the sub-Neptune TOI-2136b around a nearby M3 dwarf
    Context. The NASA space telescope TESS is currently in the extended mission of its all-sky search for new transiting planets. Of the thousands of candidates...
  • Publication
    Validation of up to seven TESS planet candidates through multi-colour transit photometry using MuSCAT2 data
    The TESS mission searches for transiting exoplanets by monitoring the brightness of hundreds of thousands of stars across the entire sky. M-type planet hosts...
  • Publication
    Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
    Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational...

    Variability of the polarization profiles of the Ba II D{2} line in the solar atmosphere
    Resonance-scattering polarization and the Hanle effect are powerful but seldom exploited probes into the magnetism of the quiet solar atmosphere. They are also...
