    The Origins of Planetary Nebulae in the Inner and Outer Disks of M 31
    The planetary nebulae (PNe) of M 31 are receiving considerable attention as probes of its structure and chemical evolution in a galactic environment that is...

    The outflow structure of NGC 6537.
    We present high and low resolution spectroscopy and narrow-band imaging of the unusual bipolar outflow source NGC 6537. As a consequence, we are able for the...

    The planetary nebula IC 4776 and its post-common-envelope binary central star
    We present a detailed analysis of IC 4776, a planetary nebula displaying a morphology believed to be typical of central star binarity. The nebula is shown to...

    The planetary nebula IPHASXJ211420.0+434136 (Ou5): insights into common-envelope dynamical and chemical evolution
    While analysing the images of the IPHAS (INT/WFC Photometric Hα Survey of the northern Galactic plane) survey, we noticed that the central star of the candidate...

    The planetary nebulae and H II regions in NGC 6822 revisited. Clues to AGB nucleosynthesis
    Aims: The chemical behaviour of an ample sample of planetary nebulae (PNe) in NGC 6822 is analysed. Methods: Spectrophotometric data of 11 PNe and two H ii...

    The post-common envelope central stars of the planetary nebulae Henize 2-155 and Henize 2-161
    We present a study of Hen 2-155 and Hen 2-161, two planetary nebulae which bear striking morphological similarities to other planetary nebulae known to host...

    The post-common-envelope binary central star of the planetary nebula ETHOS 1
    We present a detailed study of the binary central star of the planetary nebula ETHOS 1 (PN G068.1+11.0). Simultaneous modelling of light and radial velocity...

    The post-common-envelope binary central star of the planetary nebula Ou 5: a doubly eclipsing post-red-giant-branch system
    We present a detailed study of the stellar and orbital parameters of the post-common envelope binary central star of the planetary nebula Ou 5. Low-resolution...
