    Space astrometry of the very massive ˜150 M⊙ candidate runaway star VFTS682
    How very massive stars form is still an open question in astrophysics. VFTS682 is among the most massive stars known, with an inferred initial mass of ≳150 M_⊙...

    Spatial dependence of the star formation history in the central regions of the Fornax dwarf spheroidal galaxy
    We present the star formation history (SFH) and the age-metallicity relation (AMR) in three fields of the Fornax dwarf spheroidal galaxy. They sample a region...

    Spatial variations in the Milky Way disc metallicity-age relation
    Stellar ages are a crucial component to studying the evolution of the Milky Way. Using Gaia DR2 distance estimates, it is now possible to estimate stellar ages...

    Spatially resolved LMC star formation history - I. Outside in evolution of the outer LMC disc
    We study the evolution of three fields in the outer Large Magellanic Cloud (LMC) disc (Rgc = 3.5-6.2 kpc). Their star formation history indicates a stellar...

    Spatially resolved near-infrared spectroscopy of the massive star-forming region IRAS 19410+2336
    Aims: IRAS 19410+2336 is a young massive star forming region with an intense outflow activity. Outflows are frequently studied in the near-infrared (NIR) since...

    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 Classification of B Stars: The Empirical Sequence Using SDSS-IV/APOGEE Near-IR Data
    We present a semi-empirical spectral classification scheme for normal B-type stars using near-infrared (NIR) spectra (1.5-1.7 μm) from the Sloan Digital Sky...

    Spectroscopic analysis tool for intEgraL fieLd unIt daTacubEs (SATELLITE): case studies of NGC 7009 and NGC 6778 with MUSE
    Integral field spectroscopy (IFS) provides a unique capability to spectroscopically study extended sources over a 2D field of view, but it also requires new...

    Spectroscopic and physical parameters of Galactic O-type stars. I. Effects of rotation and spectral resolving power in the spectral classification of dwarfs and giants
    Context. The modern-era spectral classification of O-stars relies on either the Walborn or the Conti-Mathys scheme. Since both of these approaches have been...
