    Iron abundance and dust in galactic H II regions.
    The [Fe II] and [Fe III] emission of seven galactic H II regions is studied with the aim of comparing their gaseous Fe abundance. The [Fe II] line intensity...

    Iron Depletion in Ionized Nebulae of the Large Magellanic Cloud
    We present here preliminary results of an analysis of the iron abundance in the ionized gas of three planetary nebulae and one H II region of the Large...

    Is the supersonic turbulence observed in HII regions sustained by the presence of magnetic fields?
    We describe a set of Hα emission line profiles from populations of H II regions in nearby spiral galaxies. These are characterized by a strong Gaussian central...

    ISO observations of five giant H II regions in M101.
    The authors present ISOLWS spectra of 5 giant H II region in the spiral galaxy M101. The data, not yet fully reduced, were taken by using the medium resolution...
