    Understanding Galactic planetary nebulae with precise/reliable nebular abundances
    We compare recent precise/reliable nebular abundances - as derived from high-quality optical spectra and the most recent ICFs - in a sample of Galactic...

    Unresolved Wind-driven Shells and the Supersonic Velocity Dispersion in Giant H II Regions
    The presence of giant shells or loops in giant H II regions is clear witness to the mechanical energy input from massive stars. Here we evaluate the impact that...

    Violent star formation in NGC 2363
    We present narrowband H-alpha imaging and long-slit optical and near-infrared spectroscopy of the giant H II region NGC 2363. The spectroscopic data are taken...
