    Ca II H high-resolution spectral monitoring of active late-type dwarfs
    We have monitored Ca II H with a spectral resolution of 8 x 104, in a sample of late-type MS stars over a four-year period. The high resolution enables us to...

    Ca line formation in late-type stellar atmospheres. I. The model atom
    Context. Departures from local thermodynamic equilibrium (LTE) distort the calcium abundance derived from stellar spectra in various ways, depending on the...

    Calcium triplet metallicity calibration for stars in the Galactic bulge
    Aims: We present a new calibration of the calcium II triplet equivalent widths versus [Fe/H], constructed upon K giant stars in the Galactic bulge. This...

    Calibrating Convective Properties of Solar-like Stars in the Kepler Field of View
    Stellar models generally use simple parameterizations to treat convection. The most widely used parameterization is the so-called mixing-length theory where the...

    Calibrating the metallicity of M dwarfs in wide physical binaries with F-, G-, and K-primaries - I: High-resolution spectroscopy with HERMES: stellar parameters, abundances, and kinematics
    We investigated almost 500 stars distributed among 193 binary or multiple systems made of late-F, G-, or early-K-primaries and late-K- or M-dwarf companion...

    Calibration aspects of the JEM-EUSO mission
    The JEM-EUSO telescope will be, after calibration, a very accurate instrument which yields the number of received photons from the number of measured photo...

    Calibrations of Atmospheric Parameters Obtained from the First Year of SDSS-III APOGEE Observations
    The Sloan Digital Sky Survey III (SDSS-III) Apache Point Observatory Galactic Evolution Experiment (APOGEE) is a three-year survey that is collecting 105 high...

    CALIFA reveals prolate rotation in massive early-type galaxies: A polar galaxy merger origin?
    We present new evidence for eight early-type galaxies (ETGs) from the CALIFA Survey that show clear rotation around their major photometric axis ("prolate...

    CALIFA, the Calar Alto Legacy Integral Field Area survey. I. Survey presentation
    The final product of galaxy evolution through cosmic time is the population of galaxies in the local universe. These galaxies are also those that can be studied...
