    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...

    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...

    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...
  • Publication
    Catalog of Planetary Nebulae Detected by GALEX and Corollary Optical Surveys
    Planetary nebulae (PNs) consist of an ionized envelope surrounding a hot central star (CSPN) that emits mostly at ultraviolet (UV) wavelengths. UV observations...

    Cepheid Variable Stars in the Pegasus Dwarf Irregular Galaxy: Constraints on the Star Formation History
    Observations of the resolved stars obtained over a period of 11 years in the Local Group dwarf irregular galaxy Pegasus have been used to search for Cepheid...
  • Publication
    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...
  • Publication
    Characterization of a Sample of Intermediate-type Active Galactic Nuclei. II. Host Bulge Properties and Black Hole Mass Estimates
    We present a study of the host bulge properties and their relations with the black hole mass for a sample of 10 intermediate-type active galactic nuclei (AGNs)...
