    Unveiling the internal structure and formation history of the three planets transiting HIP 29442 (TOI-469) with CHEOPS
    Multiplanetary systems spanning the radius valley are ideal testing grounds for exploring the different proposed explanations for the observed bimodality in the...

    Unveiling the past evolution of the progenitor of the Helmi streams
    Aims: We aim to determine unique features that characterise the past evolution of the progenitor of the Helmi streams through the analysis of star formation...

    Unveiling the shape: A multi-wavelength analysis of the galaxy clusters Abell 76 and Abell 1307
    We analyse the dynamical state of the galaxy clusters Abell 76 and Abell 1307 from the optical point of view, presenting a coherent scenario that responds to...

    Unveiling the structure of the planetary nebula M 2-48:. Kinematics and physical conditions
    The kinematics and physical conditions of the bipolar planetary nebula M 2-48 are analysed from high and low dispersion long-slit spectra. Previous CCD narrow...

    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...
