We present the first instalment of a deep imaging catalogue containing 58 True, Likely, and Possible extended PNe detected with the Isaac Newton Telescope...
First Evidence of Enhanced Recombination in Astrophysical Environments and the Implications for Plasma Diagnostics
We report the first unambiguous observational evidence of Rydberg Enhanced Recombination (RER), a potentially important recombination mechanism that has...
First evidence of the possible detection of diffuse circumstellar bands in AGB descendants
The short transition phase between asymptotic giant branch stars (AGB; when circumstellar envelopes rich in small organic molecules are efficiently created) and...
First Release of the IPHAS Catalogue of Extended Planetary Nebulae
Following a vast search for extended Planetary Nebulae (PNe) in the Galactic Plane using IPHAS, we present the first release of the "IPHAS Catalogue of Extended...
First release of the IPHAS catalogue of new extended planetary nebulae
We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the...
Formation of Fullerenes in H-containing Planetary Nebulae
Hydrogen depleted environments are considered an essential requirement for the formation of fullerenes. The recent detection of C60 and C70 fullerenes in what...
Fornax 3D project: Automated detection of planetary nebulae in the centres of early-type galaxies and first results
Extragalactic planetary nebulae (PNe) are detectable through relatively strong nebulous [O III] emission and act as direct probes into the local stellar...
Galactic kinematics of Planetary Nebulae with [WC] central star
High resolution spectra are used to analyze the galactic kinematics and distribution of a sample of planetary nebulae with [WR] and `wel' central star ([WR]PN...
Galactic planetary nebulae with precise nebular abundances as a tool to understand the evolution of asymptotic giant branch stars
We present nucleosynthesis predictions (HeCNOCl) from asymptotic giant branch (AGB) models, with diffusive overshooting from all the convective borders, in the...
