    CCD-based observations of PG 0856+121 and a theoretical analysis of its oscillation modes
    BVRI CCD-based and near-IR (J) imaging, together with unfiltered photometry of the hot subdwarf B star PG 0856+121, are reported. Two close, faint, red, point...

    Census of H II regions in NGC 6754 derived with MUSE: Constraints on the metal mixing scale
    We present a study of the H II regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197 637 individual spectra, using integral field...

    Center-to-limb variation of solar line profiles as a test of NLTE line formation calculations
    We present new observations of the center-to-limb variation of spectral lines in the quiet Sun. Our long-slit spectra are corrected for scattered light, which...

    Center-to-limb variation of the area covered by magnetic bright points in the quiet Sun
    Context. The quiet Sun magnetic fields produce ubiquitous bright points (BPs) that cover a significant fraction of the solar surface. Their contribution to the...

    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...

    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 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...
