    Carbon and oxygen gradient values in recombination lines in HII regions
    The galactic gradient of C has been determined for the first time using recombination lines in HII regions. Results from these lines are more reliable than...

    CARMENES finds a nearby Neptune in the temperate zone of an early-M dwarf
    We report on the first star discovered to host a planet detected by radial velocity (RV) observations obtained within the CARMENES survey for exoplanets around...

    Challenging the theoretically predicted mass-loss rate increase of blue supergiants in the bi-stability region of the stellar winds
    The properties of blue supergiants are key for constraining the end of the main sequence phase, a phase during which massive stars spend most of their lifetimes...

    Characterization of the host galaxy from gamma-ray blazars
    The most extreme electromagnetic radiation that can be observed is known as very high energy gamma rays (VHE, E>100 GeV). It is the last window open to the...

    Chromospheric polarization in the photospheric solar oxygen infrared triplet.
    We present multilevel radiative transfer modeling of the scattering polarization observed in the solar O I infrared triplet around 777 nm. We demonstrate that...

    Circumstellar effects on the Rubidium abundances in massive AGB stars.
    Intermediate mass stars, in their last phases of evolution ("AGB stars"),produce a large number of heavy elements (rich in neutrons), some ofthem radioactive...

    Collision of C-type Ryugu’s parent body with a rocky object
    Hayabusa2’s optical navigation camera (ONC) found many anomalously bright boulders on the dark surface of the carbonaceous (or C-type) asteroid Ryugu...

    Colouring asteroid Bennu
    The main objective of the NASA OSIRIS-REx mission is the collection of material from the surface of primitive asteroid (101955) Bennu, and to bring it back to...

    Confinement of interstellar dust in galactic bars
    Tests have been carried out for the first time on the hypothesis that the structure of interstellar dust around galactic bars is determined by the velocity...
