    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...

    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...

    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...

    The Chemical Enrichment History of the Large Magellanic Cloud
    Ca II triplet spectroscopy has been used to derive stellar metallicities for individual stars in four Large Magellanic Cloud fields situated at galactocentric...
  • Publicación
    The Chemical Enrichment History of the Small Magellanic Cloud and its Gradients
    We present stellar metallicities derived from Ca II triplet spectroscopy in over 350 red giant branch stars in 13 fields distributed in different positions in...

    The chemical evolution of the dwarf spheroidal galaxy Sextans
    We present our analysis of the FLAMES dataset targeting the central 25' region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major...

    The chemo-dynamical groups of Galactic globular clusters
    We introduce a multicomponent chemo-dynamical method for splitting the Galactic population of globular clusters (GCs) into three distinct constituents: bulge...

    The Cluster HEritage project with XMM-Newton: Mass Assembly and Thermodynamics at the Endpoint of structure formation. I. Programme overview
    The Cluster HEritage project with XMM-Newton - Mass Assembly and Thermodynamics at the Endpoint of structure formation (CHEX-MATE) is a three-mega-second Multi...
