    Stellar content, planetary nebulae, and globular clusters of [KKS2000]04 (NGC 1052-DF2)
    [KKS2000]04 (NGC 1052-DF2) has become a controversial and well-studied galaxy after the claims suggesting a lack of dark matter and the presence of an...

    Stellar dynamics and dark matter in Local Group dwarf galaxies
    When interpreted within the standard framework of Newtonian gravity and dynamics, the kinematics of stars and gas in dwarf galaxies reveals that most of these...
  • Publication
    Stellar mergers as the origin of the blue main-sequence band in young star clusters
    Recent high-quality Hubble Space Telescope photometry shows that the main-sequence stars of young star clusters form two discrete components in the colour...

    Stellar metallicity gradients of Local Group dwarf galaxies
    Aims: We explore correlations between the strength of metallicity gradients in Local Group dwarf galaxies and their stellar mass, star formation history...

    Stellar migration in the Auriga simulations
    We study the presence and importance of stellar migration in the evolution of 17 Milky-Way like disc galaxies with stellar mass 10 < log(M */M ⊙) < 11 from the...
  • Publication
    Stellar Wind Variations during the X-Ray High and Low States of Cygnus X-1
    We present results from Hubble Space Telescope ultraviolet spectroscopy of the massive X-ray and black hole binary system, HD 226868 = Cyg X-1. The spectra were...

    StraKLIP: A Novel Pipeline for Detection and Characterization of Close-in Faint Companions through the Karhunen-Loéve Image Processing Algorithm
    We present a new pipeline developed to detect and characterize faint astronomical companions at small angular separation from the host star using sets of wide...
  • Publication
    Strömgren Photometry of Galactic Globular Clusters. II. Metallicity Distribution of Red Giants in ω Centauri
    We present new intermediate-band Strömgren photometry based on more than 300 u, v, b, y images of the Galactic globular cluster ω Cen. Optical data were...

    Strong chemical tagging with APOGEE: 21 candidate star clusters that have dissolved across the Milky Way disc
    Chemically tagging groups of stars born in the same birth cluster is a major goal of spectroscopic surveys. To investigate the feasibility of such strong...
