    A high-resolution study of near-IR diffuse interstellar bands, search for small-scale structure, time variability, and stellar features
    Context. The diffuse interstellar bands (DIBs) are a set of hundreds of unidentified absorption features that appear almost ubiquitously throughout the...

    A high-resolution three-dimensional model of the solar photosphere derived from Hinode observations
    A new three-dimensional model of the solar photosphere is presented in this paper and made publicly available to the community. This model has the peculiarity...

    A high-resolution VLT/FLAMES study of individual stars in the centre of the Fornax dwarf spheroidal galaxy
    For the first time we show the detailed, late-stage, chemical evolution history of a small nearby dwarf spheroidal galaxy in the Local Group. We present the...
