    The Cetus-Palca stream: A disrupted small dwarf galaxy. A prequel to the science possible with WEAVE with precise spectro-photometric distances
    We present a new fully data-driven approach to derive spectro-photometric distances based on artificial neural networks. The method was developed and tested on...

    The chemical composition of carbon stars. The R-type stars
    Aims. The aim of this work is to shed some light on the problem of the formation of carbon stars of R-type from a detailed study of their chemical composition...

    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...

    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...

    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 enrichment by massive stars in Wolf-Rayet galaxies.
    We present stellar population models for starbursts in a sample of eleven Wolf-Rayet galaxies. Taking into account the observational data available, we try to...
