3D Photoionisation Modelling of NGC 6302
N. J. Wright, M. J. Barlow, B. Ercolano +1
We present a three-dimensional photoionisation and dust radiative transfer model of NGC 6302, an extreme, high-excitation planetary nebula. We use the 3D photoionisation code Mocas…
bHROS high spectral resolution observations of PN forbidden and recombination line profiles
M. J. Barlow, A. S. Hales, P. J. Storey +3
We have acquired high spectral resolution observations (R=150,000) of the planetary nebulae NGC 7009 and NGC 6153, using bHROS on Gemini South. Observations of this type may provid…
Integrated spectrum of the planetary nebula NGC 7027
Y. Zhang, X. -W. Liu, S. -G. Luo +2
We present deep optical spectra of the archetypal young planetary nebula (PN) NGC 7027, covering a wavelength range from 3310 to 9160 A. The observations were carried out by unifor…
A deep survey of heavy element lines in planetary nebulae -- II. Recombination line abundances and evidence for ultra-cold plasma
Y. G. Tsamis, M. J. Barlow, X. -W. Liu +2
[Abridged] Deep optical observations of the spectra of 12 Galactic planetary nebulae (PNe) and 3 Magellanic Cloud PNe were presented in Paper I by Tsamis et al. (2003b), who carrie…
The coronal line regions of planetary nebulae NGC6302 and NGC6537: 3-13um grating and echelle spectroscopy
Simon Casassus, Patrick F. Roche, Mike J. Barlow
We report on advances in the study of the cores of NGC6302 and NGC6537 using infrared grating and echelle spectroscopy. In NGC6302, emission lines from species spanning a large ran…
