Two-colour photometry of the binary planetary nebula nuclei UU Sagitte and V477 Lyrae: oversized secondaries in post-common-envelope binaries

open access: yes, 2008
We present new V- and R-passband CCD photometry of UU Sge and V477 Lyr, the eclipsing binary nuclei of the planetary nebulae Abell 63 and Abell 46, respectively.

Mid-infrared observations of planetary nebulae Detected in the glimpse 3d survey

open access: yes, 2011
We present mapping, profiles and photometry for 24 planetary nebulae (PNe) detected in the GLIMPSE 3D mid-infrared (MIR) survey of the Galactic plane. The PNe show many of the properties observed in previous studies of these sources, including evidence ...

A possible observational measure of evolution in bipolar nebulae

open access: yes, 2002
Bipolar planetary nebulae (BPNe) possess a broad range of shapes, ranging from narrow-waisted butterfly-like structures, through to those which are more nearly cylindrical.

Indications of a large fraction of spectroscopic binaries among nuclei of planetary nebulae

open access: yes, 2004
Previous work indicates that about 10% of planetary-nebula nuclei (PNNi) are photometrically variable short-period binaries with periods of hours to a few days.

Modelling ionised and photodissociated regions

open access: yes, 2010
The bulk of the mass in star-forming environments is contained in photodissociated regions (PDRs) where the chemistry is controlled by the far ultraviolet radiation field coming from nearby ionizing sources.

Spectroscopic survey of faint planetary-nebula nuclei

open access: yes
We present an analysis of 17 H-rich central stars of planetary nebulae (PNe) observed in our spectroscopic survey of nuclei of faint Galactic PNe carried out at the 10-m Hobby-Eberly Telescope.
