    Detection of New Planetary Nebulae by IPHAS, the Hα Survey of the North Galactic Plane
    IPHAS is an ongoing Hα imaging survey of the North Galactic plane. When completed, it is expected to discover several hundred new Galactic planetary nebulae, in...

    Detection of the [C I] λ8727 emission line. Low-ionization structures in NGC 7009
    We report the first spatially resolved detection of the near-infrared [C I] λ8727 emission from the outer pair of low-ionization structures in the planetary...

    Diffuse Interstellar Bands in (Proto-) Fullerene-Rich Environments
    The recent infrared detection of fullerenes (C60 and C70) in Planetary Nebulae (PNe) and R Coronae Borealis (RCB) stars offers a beautiful opportunity for...

    Diffuse interstellar bands in fullerene planetary nebulae: the fullerenes - diffuse interstellar bands connection
    We present high-resolution (R ~ 15 000) VLT/UVES optical spectra of two planetary nebulae (PNe; Tc 1 and M 1-20) where C60 (and C70) fullerenes have already...

    Diffuse Light in Galaxy Groups
    We have studied the amount of diffuse light in two galaxy groups, Leo and HCG 44 through the detection of intragroup planetary nebulae (IGPNe). The emission...

    Discovery of a planetary nebula surrounding the symbiotic star DT Serpentis
    We report the discovery of a planetary nebula centered on the poorly studied symbiotic binary star DT Ser. In a few other symbiotic stars spatially resolved...

    Discovery of an eclipsing dwarf nova in the ancient nova shell Te 11
    We report on the discovery of an eclipsing dwarf nova (DN) inside the peculiar, bilobed nebula Te 11. Modelling of high-speed photometry of the eclipse finds...

    Discovery of close binary central stars in the planetary nebulae NGC 6326 and NGC 6778
    We present observations proving the close binary nature of the central stars belonging to the planetary nebulae (PNe) NGC 6326 and NGC 6778. Photometric...

    Dissecting NGC 3132: tracing the mass-loss history of the southern ring planetary nebula
    Central to our understanding of stellar evolution and its impact on processes in our Galaxy and across the Universe is the study of mass-loss. While the general...
