    The MUSE view of the planetary nebula NGC 3132
    Aims: Two-dimensional spectroscopic data for the whole extent of the NGC 3132 planetary nebula have been obtained. We deliver a reduced data-cube and high...

    The nature and structure of the emission line nebula K3-35: a very young planetary nebula with precessing bipolar jet-like outflows?
    We present Hα, [NII]6583 and 6-cm continuum images of the emission line nebula K3-35. The optical images reveal an extended nebula (size ~=11x9arcsec^2 in [NII]...

    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 Low-Ionization Microstructures in PNe
    We discuss here the nature of a rich zoo of knots, filaments, jets and jet-like systems, located--in terms of morphology and kinematics--either inside or...

    The Necklace planetary nebula: equatorial and polar outflows from a post-common-envelope system
    We present the discovery of a new planetary nebula from the IPHAS survey. The remarkable morphology of its inner regions, which display a bright knotty ring...

    The Necklace: equatorial and polar outflows from the binary central star of the new planetary nebula IPHASX J194359.5+170901
    IPHASX J194359.5+170901 is a new high-excitation planetary nebula with remarkable characteristics. It consists of a knotty ring expanding at a speed of 28 km s...

    The Onset of Photoionization in Post-AGB Stars
    During the post-AGB phase the dust shell detaches from the central star and dust temperatures varies between 100 and 200 K. In order to study the onset of photo...

    The origin of the most luminous Planetary Nebulae
    As part of a systematic effort to characterize the properties and progenitors of the most luminous planetary nebulae (PNe), we obtained a sample among the...

    The origin of the planetary nebula M 1-16. A morpho-kinematic and chemical analysis
    We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a...
