    Center-to-limb variations of the He I 10 830 Å triplet
    We present high-resolution spectroscopic observations of the quiet-Sun center-to-limb variations (CLV) of the He I triplet at 10 830 Å and the nearby Si I 10...

    Central star formation and metallicity in CALIFA interacting galaxies
    We use optical integral-field spectroscopic (IFS) data from 103 nearby galaxies at different stages of the merging event, from close pairs to merger remnants...

    Centre-to-limb variation of solar granulation in the infrared
    Broad-band images have been obtained at the extremes of the continuum absorption coefficient of the solar atmosphere, at lambda 0.8 mu m and lambda 1.55 mu m...

    CGCS 6306, another X-ray-emitting asymptotic giant branch star confirmed to be a symbiotic binary
    Context. A number of asymptotic giant branch (AGB) stars are known to exhibit UV excess and/or X-ray emission. These have been considered signposts of a hot...

    Chandra follow-up of bursters with low persistent emission
    We report on Chandra ACIS-S observations of five type I X-ray bursters with low persistent emission: SAX J1324.5-6313, SAX J1752.3-3128, SAX J1752.3-3128I, SAX...

    Characterisation of extrasolar planetary transit candidates. II. The companions to late M-type stars
    We present a second paper of a complete characterization of stars whose low-depth transits were discovered by the OGLE-III campaign to select the most promising...

    Characterisation of local halo building blocks: Thamnos and Sequoia
    Context. A crucial aspect of galaxy evolution is the pace at which galaxies build up their mass. We can investigate this hierarchical assembly by uncovering and...

    Characterisation of the new target of the NASA Lucy mission: Asteroid 152830 Dinkinesh (1999 VD57)
    Context. The NASA Lucy mission is designed to collect data that will be used to study the very interesting population of Jupiter Trojans, which are considered...

    Characterisation of the TOI-421 planetary system using CHEOPS, TESS, and archival radial velocity data
    Context. The TOI-421 planetary system contains two sub-Neptune-type planets (P b ~ 5.2 days, T eq, b ~ 900 K, and P c ~ 16.1 days, T eq,c ~ 650 K) and is a...
