    Carbon and nitrogen abundances of individual stars in the Sculptor dwarf spheroidal galaxy
    We present [C/Fe] and [N/Fe] abundance ratios and CH(λ4300) and S(λ3883) index measurements for 94 red giant branch (RGB) stars in the Sculptor dwarf spheroidal...

    Carbon and nitrogen abundances of stellar populations in the globular cluster M 2
    We present CH and CN index analysis and C and N abundance calculations based on the low-resolution blue spectra of red giant branch (RGB) stars in the Galactic...

    Carbon enrichment in APOGEE disk stars as evidence of mass transfer in binaries
    Context. Carbon abundances in first-ascent giant stars are usually lower than those of their main-sequence counterparts. At moderate metallicities, stellar...

    Carbon stars in the X-Shooter Spectral Library⋆⋆⋆
    We provide a new collection of spectra of 35 carbon stars obtained with the ESO/VLT X-Shooter instrument as part of the X-Shooter Spectral Library project. The...

    CARMENES detection of the Ca II infrared triplet and possible evidence of He I in the atmosphere of WASP-76b
    Ultra-hot Jupiters are highly irradiated gas giants with equilibrium temperatures typically higher than 2000 K. Atmospheric studies of these planets have shown...

    CARMENES input catalog of M dwarfs. VII. New rotation periods for the survey stars and their correlations with stellar activity
    Aims: Knowledge of rotation periods (P rot) is important for understanding the magnetic activity and angular momentum evolution of late-type stars, as well as...

    CARMENES input catalogue of M dwarfs. II. High-resolution imaging with FastCam
    Aims: We search for low-mass companions of M dwarfs and characterize their multiplicity fraction with the purpose of helping in the selection of the most...

    CARMENES input catalogue of M dwarfs. IV. New rotation periods from photometric time series
    Aims: The main goal of this work is to measure rotation periods of the M-type dwarf stars being observed by the CARMENES exoplanet survey to help distinguish...
