    Comparison of theoretical and observed Ca II 8542 Stokes profiles in quiet regions at the centre of the solar disc
    Context. Interpreting the Stokes profiles observed in quiet regions of the solar chromosphere is a challenging task. The Stokes Q and U profiles are dominated...

    Compositional study of asteroids in the Erigone collisional family using visible spectroscopy at the 10.4 m GTC
    Two primitive near-Earth asteroids, (101955) Bennu and (162173) Ryugu, will be visited by a spacecraft with the aim of returning samples back to Earth. Since...

    Confidence levels of evolutionary synthesis models
    The stochastic nature of the IMF in young stellar clusters implies that clusters of the same mass and age do not present the same unique values of their...

    Confidence levels of evolutionary synthesis models. II. On sampling and Poissonian fluctuations
    In terms of statistical fluctuations, stellar population synthesis models are only asymptotically correct in the limit of a large number of stars, where...

    Confidence limits of evolutionary synthesis models. III. On time-integrated quantities
    Evolutionary synthesis models are a fundamental tool to interpret the properties of observed stellar systems. In order to achieve a meaningful comparison...
