    Solar Space Density of the Red Clump Stars and the Scale-Length of the Thin Disc
    We estimated the scale-length of the thin disc with the J and W1 magnitudes of the most probable red clump stars in the Galactic plane, - 0°.5 ⩽ b ⩽ +0°.5, in...

    Solar-like oscillations in γ Cephei A as seen through SONG and TESS. A seismic study of γ Cephei A
    Context. Fundamental stellar parameters such as mass and radius are some of the most important building blocks in astronomy, both when it comes to understanding...

    Solid state debromination of C 60 Br 24 back to C 60 with cesium iodide: kinetics, thermodynamics and mechanism
    The bromofullerene C60Br24 undergoes a complete and quantitative debromination to C60 when it is mixed and ground in the solid state with cesium iodide (CsI)...

    Solid state radiolysis of amino acids in an astrochemical perspective
    The aliphatic amino acids L-alanine and L-leucine and the aromatic amino acids L-phenylalanine, L-tyrosine and L-tryptophan were irradiated in the solid state...

    Solo dwarfs - III. Exploring the orbital origins of isolated Local Group galaxies with Gaia Data Release 2
    We measure systemic proper motions for distant dwarf galaxies in the Local Group and investigate if these isolated galaxies have ever had an interaction with...

    Solo dwarfs II: the stellar structure of isolated Local Group dwarf galaxies
    The Solo (Solitary Local) Dwarf Galaxy survey is a volume-limited, wide-field g- and i-band survey of all known nearby (<3 Mpc) and isolated (>300 kpc from the...

    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...
