    Spindown of massive single main sequence stars in the Milky Way
    Context. We need to understand the spin evolution of massive stars to compute their internal rotation-induced mixing processes, isolate effects of close binary...

    Spiral-shaped wavefronts in a sunspot umbra
    Context. Solar active regions show a wide variety of oscillatory phenomena. The presence of the magnetic field leads to the appearance of several wave modes...

    SSSPM J1102-3431: A probable new young brown dwarf member of the TW Hydrae Association
    We have used archival survey data, most importantly from the SuperCOSMOS Sky Surveys, to derive accurate proper motions and thus confirm the membership of two...

    SSSPM J1444-2019: An extremely high proper motion, ultracool subdwarf
    We present the discovery of a new extreme high proper motion object (˜3.5 arcsec/year) which we classify as an ultracool subdwarf with [M/H] ˜ -0.5. It has a...
