    Abundance ratios of volatile vs. refractory elements in planet-harbouring stars: hints of pollution?
    We present the [ X/H] trends as a function of the elemental condensation temperature TC in 88 planet host stars and in a volume-limited comparison sample of 33...

    Abundance to age ratios in the HARPS-GTO sample with Gaia DR2. Chemical clocks for a range of [Fe/H]
    Aims: The purpose of this work is to evaluate how several elements produced by different nucleosynthesis processes behave with stellar age and provide empirical...

    Abundance trend with condensation temperature for stars with different Galactic birth places
    Context. During the past decade, several studies reported a correlation between chemical abundances of stars and condensation temperature (also known as Tc...
  • Publication
    Abundance variations in the planetary nebula A 78
    The authors present long slit low dispersion flux calibrated spectra for the planetary nebula A 78, and from these they obtain the chemical abundances and their...

    Abundances of Be-9 in a sample of highly metal-deficient dwarfs - Implications for early galactic nucleosynthesis and primordial lithium
    We have observed six highly metal-deficient dwarfs in the spectral range containing the resonance doublet of 9Be II at 3130 Å. Using the method of spectral...

    Abundances of disk and bulge giants from high-resolution optical spectra. I. O, Mg, Ca, and Ti in the solar neighborhood and Kepler field samples
    Context. The Galactic bulge is an intriguing and significant part of our Galaxy, but it is hard to observe because it is both distant and covered by dust in the...
  • Publication
    Abundances of disk and bulge giants from high-resolution optical spectra. II. O, Mg, Co, and Ti in the bulge sample
    Context. Determining elemental abundances of bulge stars can, via chemical evolution modeling, help to understand the formation and evolution of the bulge...
  • Publication
    Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE
    Context. Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment...
  • Publication
    Abundances of light metals and NI in a sample of disc stars
    High resolution, high S/N spectra obtained using RETICON and CCD detectors are used to determine the abundances of Al, Si, Ca, Ni and Fe in 23 disc stars in the...
