    Spectral analysis of the barium central star of the planetary nebula Hen 2-39
    Context. Barium stars are peculiar red giants characterized by an overabundance of the elements synthesized in the slow neutron-capture nucleosynthesis (s...

    Spectral characterisation of 14 V-type candidate asteroids from the MOVIS catalogue
    Most of the currently known basaltic (V-type) asteroids are believed to be past or present members of the Vesta dynamical family. The rising discoveries of V...

    Spectral signature of uncombed penumbral magnetic fields
    The uncombed penumbral model proposed by Solanki & Montavon (cite{sol93a}) is used to understand some recent observational results found in penumbrae. This...

    Spectral signature of uncombed penumbral magnetic fields. Comment
    The conservation of magnetic flux demands a magnetic field fine structure as small as 15 km to explain the net circular polarization observed in penumbrae...

    Spectral signature of uncombed penumbral magnetic fields. Reply
    A combination of two penumbral models similar to those used by Martínez Pillet (2000) is presented. One matches the observed rms fluctuations perfectly while...

    Spectro-photometric close pairs in GOODS-S: major and minor companions of intermediate-mass galaxies
    Aims: Recent work has shown that major mergers of disc galaxies can only account for 20% of the growth of the galaxy red sequence between z = 1 and z = 0. Our...
