    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...

    Comprehensive comparison between APOGEE and LAMOST. Radial velocities and atmospheric stellar parameters
    Context. In the era of massive spectroscopy surveys, automated stellar parameter pipelines and their validation are extremely important for an efficient...

    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...

    Confidence limits of evolutionary synthesis models. IV. Moving forward to a probabilistic formulation
    Context: .Synthesis models predict the integrated properties of stellar populations. Several problems exist in this field, mostly related to the fact that...

    Confirmation and characterisation of three giant planets detected by TESS from the FIES/NOT and Tull/McDonald spectrographs
    We report the confirmation and characterisation of TOI-1820 b, TOI-2025 b, and TOI-2158 b, three Jupiter-sized planets on short-period orbits around G-type...
