    The intriguing H I gas in NGC 5253: an infall of a diffuse, low-metallicity H I cloud?
    We present new, deep H I line and 20-cm radio-continuum data of the very puzzling blue compact dwarf galaxy NGC 5253, obtained with the Australia Telescope...

    The Intriguing Stellar Populations in the Globular Clusters NGC 6388 and NGC 6441
    NGC 6388 and NGC 6441 are two massive Galactic bulge globular clusters that share many properties, including the presence of an extended horizontal branch (HB)...

    The ionised and molecular mass of post-common-envelope planetary nebulae. The missing mass problem
    Context. Most planetary nebulae (PNe) show beautiful, axisymmetric morphologies despite their progenitor stars being essentially spherical. Close binarity is...

    The ionized gas at the centre of IC 10: a possible localized chemical pollution by Wolf-Rayet stars
    We present results from integral field spectroscopy with the Potsdam Multi-Aperture Spectrograph at the 3.5-m telescope at Calar Alto Observatory of the intense...

    The ionizing radiation from massive stars and its impact on HII regions: results from modern model atmospheres
    We present a detailed comparison of the ionizing spectral energy distributions (SEDs) predicted by four modern stellar atmosphere codes, TLUSTY, CMFGEN, WM...

    The ISLAnds Project. III. Variable Stars in Six Andromeda Dwarf Spheroidal Galaxies
    We present a census of variable stars in six M31 dwarf spheroidal satellites observed with the Hubble Space Telescope. We detect 870 RR Lyrae (RRL) stars in the...

    The kinematic behaviour of optical recombination lines and collisionally excited lines in Galactic planetary nebulae*†
    The kinematics of the plasma in 14 planetary nebulae (PNe) is analysed by measuring the expansion velocities (Vexp) of different ions as derived from their...

    The Large Magellanic Cloud as a laboratory for hot bottom burning in massive asymptotic giant branch stars
    We use Spitzer observations of the rich population of asymptotic giant branch (AGB) stars in the Large Magellanic Cloud (LMC) to test models describing the...
