    The Ca+ abundance of HVC complex C
    We report the first detection of Ca II H and K absorption in the high-velocity cloud complex C, the largest HVC. Absorption is detected in the spectra of the...

    The CALIFA survey across the Hubble sequence. Spatially resolved stellar population properties in galaxies
    Various different physical processes contribute to the star formation and stellar mass assembly histories of galaxies. One important approach to understanding...

    The CALIFA view on stellar angular momentum across the Hubble sequence
    We present the apparent stellar angular momentum over the optical extent of 300 galaxies across the Hubble sequence using integral-field spectroscopic (IFS)...

    The Carina Project. VIII. The α-element abundances
    We have performed a new abundance analysis of Carina red giant (RG) stars from spectroscopic data collected with UVES (high spectral resolution) and FLAMES...

    The CARMENES search for exoplanets around M dwarfs . First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems
    Context. The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M dwarfs included in the CARMENES sample had been...

    The CARMENES search for exoplanets around M dwarfs. A deep learning approach to determine fundamental parameters of target stars
    Existing and upcoming instrumentation is collecting large amounts of astrophysical data, which require efficient and fast analysis techniques. We present a deep...

    The CARMENES search for exoplanets around M dwarfs. A deep transfer learning method to determine T<SUB>eff</SUB> and [M/H] of target stars
    The large amounts of astrophysical data being provided by existing and future instrumentation require efficient and fast analysis tools. Transfer learning is a...

    The CARMENES search for exoplanets around M dwarfs. A long-period planet around GJ 1151 measured with CARMENES and HARPS-N data
    Context. Detecting a planetary companion in a short-period orbit through radio emission from the interaction with its host star is a new prospect in exoplanet...

    The CARMENES search for exoplanets around M dwarfs. A Neptune-mass planet traversing the habitable zone around HD 180617
    Despite their activity, low-mass stars are of particular importance for the search of exoplanets by the means of Doppler spectroscopy, as planets with lower...
