We present the first detailed spatiokinematical analysis and modelling of the planetary nebula Shapley 1 (Sp 1), which is known to contain a close-binary central star system. Close-binary central stars have been identified as a likely source of shaping in planetary nebulae, but with little observational support to date. Deep narrow-band imaging in the light of [O III] λ5007A suggests the presence of a large bow shock to the west of the nebula, indicating that it is undergoing the first…

We present the first detailed spatio-kinematical analysis and modelling of the planetary nebula HaTr 4, one of few known to contain a post-common-envelope central star system. Common-envelope
Observational Confirmation of a Link between Common Envelope Binary Interaction and Planetary Nebula Shaping
A current issue in the study of planetary nebulae with close binary central stars is the extent to which the binaries affect the shaping of the nebulae. Recent studies have begun to show a high
Spatio-kinematic modelling of Abell 65, a double-shelled planetary nebula with a binary central star
We present the first detailed spatio-kinematical analysis and modelling of the planetary nebula Abell 65, which is known to host a post-common envelope, binary, central star system. As such, this

Context. The mechanisms that form extreme bipolar planetary nebulae remain unclear. Aims. The physical properties, structure, and dynamics of the bipolar planetary nebula, MyCn 18, are investigated
Two rings but no fellowship: LoTr 1 and its relation to planetary nebulae possessing barium central stars
LoTr 1 is a planetary nebula thought to contain an intermediate-period binary central star system (that is, a system with an orbital period, P, between 100 and, say, 1500 d). The system shows the
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 planetary nebula
Binary stars as the key to understanding planetary nebulae
Planetary nebulae are traditionally considered to represent the final evolutionary stage of all intermediate-mass stars ($\sim$0.7-8Msol). Recent evidence seems to contradict this picture. In
Binary Central Stars of Planetary Nebulae Discovered Through Photometric Variability III: The Central Star of Abell 65
