    Using autoencoders and deep transfer learning to determine the stellar parameters of 286 CARMENES M dwarfs
    Context. Deep learning (DL) techniques are a promising approach among the set of methods used in the ever-challenging determination of stellar parameters in M...

    Using binary statistics in Taurus-Auriga to distinguish between brown dwarf formation processes
    Context. One of the key questions of the star formation problem is whether brown dwarfs (BDs) form in the manner of stars directly from the gravitational...

    Using color photometry to separate transiting exoplanets from false positives
    The radial velocity technique is currently used to classify transiting objects. While capable of identifying grazing binary eclipses, this technique cannot...

    Using globular clusters to test gravity in the weak acceleration regime
    We have carried out a study of the velocity dispersion of the stars in the outskirts of the globular cluster omega Cen, finding that the velocity dispersion...

    Using globular clusters to test gravity in the weak acceleration regime: NGC 7099
    Aims:A test of Newton's law of gravity in the low acceleration regime using globular clusters is presented and new results for the core collapsed globular...

    Using population synthesis of massive stars to study the interstellar medium near OB associations
    Aims: We study the massive stars in OB associations and their surrounding interstellar medium environment, using a population synthesis code. Methods: We...

    Using radial velocities to reveal black holes in binaries: A test case
    Aims: Large radial velocity variations in the LAMOST spectra of giant stars have been used to infer the presence of unseen companions. Some of them have been...

    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...

    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...
