    C, S, Zn and Cu abundances in planet-harbouring stars
    We present a detailed and uniform study of C, S, Zn and Cu abundances in a large set of planet host stars, as well as in a homogeneous comparison sample of...
  • Publication
    C/2020 F3 (NEOWISE) production rates from high-resolution TNG/HARPS-N spectra
    The composition of comets hold clues about the early stages of the formation and evolution of the Solar System. Being the brightest comet observed in the...
  • Publication
    C/O ratios in planetary nebulae with dual-dust chemistry from faint optical recombination lines
    We present deep high-resolution (R ˜ 15 000) and high-quality UVES optical spectrophotometry of nine planetary nebulae with dual-dust chemistry. We compute...
  • Publication
    C/O vs. Mg/Si ratios in solar type stars: The HARPS sample
    Context. Aims: We aim to present a detailed study of the magnesium-to-silicon and carbon-to-oxygen ratios (Mg/Si and C/O) and their importance in determining...
  • Publication
    Ca II 8542 Å brightenings induced by a solar microflare
    Aims: We study small-scale brightenings in Ca II 8542 Å line-core images to determine their nature and effect on localized heating and mass transfer in active...
  • Publication
    Ca II H and K and Hα, and Li abundances in the pleiades late K main-sequence
    We have observed seven main sequence stars in the Pleiades, with B - V between 0.98 and 1.41 (5100-3900 K), and with a wide range of rotational velocities, in...
  • Publication
    CA II H emission line cores of late-type dwarfs - Variability measurements and velocity field diagnostics
    High-resolution spectra of Alpha Cen B, Xi Boo A, 70 Oph A, and Epsilon Ind obtained using the Coude Echelle Spectrometer and the 1.4-m Coude Auxiliary...
  • Publication
    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...
  • Publication
    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...
