    BVRJK Photometry and a Spectroscopic Study of the Algol Short-Period Binary VV Ursae Majoris
    We present the first light curves in the infrared J and K filters of VV UMa and analyze them, together with a new set of BVR light curves obtained in different...

    C and N abundances of main sequence and subgiant branch stars in NGC 1851
    We present the first chemical analysis of stars on the double subgiant branch (SGB) of the globular cluster NGC 1851. We obtained 48 Magellan IMACS spectra of...
  • Publication
    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...

    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...
