    The mixed chemistry phenomenon in Galactic Bulge PNe
    Aims: We investigate the dual-dust chemistry phenomenon in planetary nebulae (PNe) and discuss reasons for its occurrence, by analyzing Spitzer/IRS spectra of a...

    The Na-O anticorrelation in horizontal branch stars. IV. M 22
    We obtained high-resolution spectra for 94 candidate stars belonging to the HB of M 22 with FLAMES. Previous works have indicated that this cluster has split...

    The nature and origin of substructure in the outskirts of M31 - II. Detailed star formation histories
    While wide-field surveys of M31 have revealed much substructure at large radii, understanding the nature and origin of this material is not straightforward from...

    The Nature of Dust in Compact Galactic Planetary Nebulae from Spitzer Spectra
    We present the Spitzer/Infrared Spectrograph (IRS) spectra of 157 compact Galactic planetary nebulae (PNe). These young PNe provide insight on the effects of...

    The nature of HH 223 from long-slit spectroscopy
    Context: HH 223 is a knotty, undulating nebular emission of ˜30 arcsec length found in the L723 star-forming region. It lies projected onto the largest...

    The Nature of Starbursts. I. The Star Formation Histories of Eighteen Nearby Starburst Dwarf Galaxies
    We use archival Hubble Space Telescope observations of resolved stellar populations to derive the star formation histories (SFHs) of 18 nearby starburst dwarf...

    The Nature of Starbursts. II. The Duration of Starbursts in Dwarf Galaxies
    The starburst phenomenon can shape the evolution of the host galaxy and the surrounding intergalactic medium. The extent of the evolutionary impact is partly...

    The nature of the Cygnus extreme B supergiant 2MASS J20395358+4222505
    2MASS J20395358+4222505 is an obscured early B supergiant near the massive OB star association Cygnus OB2. Despite its bright infrared magnitude (K s = 5.82) it...

    The nature of V39: an LBV candidate or LBV impostor in the very low metallicity galaxy IC 1613?
    Context. Very few examples of luminous blue variable (LBV) stars or LBV candidates (LBVc) are known, particularly at metallicities below that of the Small...
