    CAPOS: The bulge Cluster APOgee Survey. I. Overview and initial ASPCAP results
    Context. Bulge globular clusters (BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until...

    Carbon Abundances in Compact Galactic Planetary Nebulae: An Ultraviolet Spectroscopic Study with the Space Telescope Imaging Spectrograph (STIS)
    We surveyed a sample of compact Galactic planetary nebulae (PNe) with the Space Telescope Imaging Spectrograph on the Hubble Space Telescope (HST) to determine...
  • Publication
    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...
  • Publication
    Carbon and oxygen abundances from recombination lines in low-metallicity star-forming galaxies. Implications for chemical evolution
    We present deep echelle spectrophotometry of the brightest emission-line knots of the star-forming galaxies He 2-10, Mrk 1271, NGC 3125, NGC 5408, POX 4, SDSS...
  • Publication
    Carbon and oxygen in H II regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
    We present C and O abundances in the Magellanic Clouds derived from deep spectra of H II regions. The data have been taken with the Ultraviolet-Visual Echelle...
  • Publication
    Carbon dust in the evolved born-again planetary nebulae A 30 and A 78
    We present an infrared (IR) characterization of the born-again planetary nebulae (PNe) A 30 and A 78 using IR images and spectra. We demonstrate that the carbon...
  • Publication
    Carbon, nitrogen, and oxygen abundance gradients in M101 and M31
    We present deep spectrophotometry of 18 H II regions in the nearby massive spiral galaxies M 101 and M 31. We have obtained direct determinations of electron...
  • Publication
    Carbon-enhanced metal-poor stars enriched in s-process and r-process elements
    We present an on-going project consisting of analysis of a sample of twenty-five metal-poor stars, most of them carbon-enriched and thus tagged carbon-enhanced...
  • Publication
    CARMENES input catalogue of M dwarfs. V. Luminosities, colours, and spectral energy distributions
    Context. The relevance of M dwarfs in the search for potentially habitable Earth-sized planets has grown significantly in the last years. Aims: In our on-going...
