    Spinning out of focus: The challenge of rotational line broadening in exoplanet reflection spectroscopy
    Context. Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour...

    Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
    In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and...

    Spinor extended Lorentz-force-like equations as consequence of a spinorial structure of space-time
    As previously shown, the special relativistic dynamical equation of the Lorentz force type can be regarded as a consequence of a succession of space-time...

    Spinor: Visible and Infrared Spectro-Polarimetry at the National Solar Observatory
    The Spectro-Polarimeter for Infrared and Optical Regions (SPINOR) is a new spectro-polarimeter that will serve as a facility instrument for the Dunn Solar...

    Spins and shapes of basaltic asteroids and the missing mantle problem
    Basaltic V-type asteroids are common in the inner part of the Main Asteroid Belt and much less abundant in the mid and outer parts. They are of scientific...

    Spiral Inflow Feeding the Nuclear Starburst in M83, Observed in Hα Emission with the GHαFaS Fabry-Perot Interferometer
    We present observations of the nearby barred starburst galaxy M83 (NGC 5236), with the new Fabry-Perot interferometer GHαFaS mounted on the 4.2 m William...

    Spiral shocks in the accretion disc of IP Peg during outburst maximum
    In response to our recent discovery of spiral arms in the accretion disc of IP Peg during rise to outburst, we have obtained time-resolved spectrophotometry of...

    Spiral structure in barred galaxies. Observational constraints to spiral arm formation mechanisms
    A method, which we have developed for determining corotation radii, has allowed us to map in detail the radial resonant structures of barred spiral galaxies...

    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...
