    The chemical composition of the Galactic H II regions M8 and M17. A revision based on deep VLT echelle spectrophotometry
    We present new echelle spectrophotometry of the Galactic H II regions M8 and M17. The data have been taken with the VLT UVES echelle spectrograph in the 3100 to...

    The chemical composition of the Orion star forming region. I. Homogeneity of O and Si abundances in B-type stars
    Context. Recent accurate abundance analyses of B-type main sequence stars in the solar vicinity has shown that abundances derived from these stellar objects are...
  • Publication
    The chemical composition of the Orion star forming region. II. Stars, gas, and dust: the abundance discrepancy conundrum
    Aims: We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance...
  • Publication
    The chemical composition of the Orion star forming region. III. C, N, Ne, Mg, and Fe abundances in B-type stars revisited
    Context. Early B-type stars are invaluable indicators of elemental abundances of their birth environments. In contrast to the surrounding neutral interstellar...

    The chemical composition of the post-asymptotic giant branch F supergiant CRL 2688
    We present an analysis of a high-resolution (R ˜ 50 000) optical spectrum of the central region of the protoplanetary nebula CRL 2688. This object is thought to...
  • Publication
    The chemical composition of TS 01, the most oxygen-deficient planetary nebula. AGB nucleosynthesis in a metal-poor binary star
    The planetary nebula TS 01 (also called PN G 135.9+55.9 or SBS 1150+599A) with its record-holding low oxygen abundance and its double degenerate close binary...
  • Publication
    The chemical compositions of accreted and in situ galactic globular clusters according to SDSS/APOGEE
    Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical...
  • Publication
    The chemical compositions of Galactic disc F and G dwarfs
    Photospheric abundances are presented for 27 elements from carbon to europium in 181 F and G dwarfs from a differential local thermodynamic equilibrium (LTE)...
  • Publication
    The chemical content of nearby galaxies from planetary nebulae: NGC 147
    We report the results of spectroscopic observations, obtained with the Gemini Multi-Object Spectrograph, of eight planetary nebulae (PNe) in the dwarf...
