Heavy elements in Galactic and Magellanic Cloud HII regions: recombination-line versus forbidden-line abundances
Yiannis G. Tsamis, M. J. Barlow, X. -W. Liu +2
We have obtained deep optical, long-slit spectrophotometry of the Galactic HII regions M 17, NGC 3576 and of the Magellanic Cloud HII regions 30 Doradus, LMC N11B and SMC N66, reco…
Three-dimensional photoionization modelling of the planetary nebula NGC 3918
B. Ercolano, C. Morisset, M. J. Barlow +2
The three-dimensional Monte Carlo photoionization code Mocassin has been applied to construct a realistic model of the planetary nebula NGC 3918. Three different geometric models w…
Mocassin: A fully three-dimensional Monte Carlo photoionization code
B. Ercolano, M. J. Barlow, P. J. Storey +1
The study of photoionized environments is fundamental to many astrophysical problems. Up to the present most photoionization codes have numerically solved the equations of radiativ…
Discovery of an edge-on dust disk around the [WC10] central star CPD-568032
Orsola De Marco, M. J. Barlow, M. Cohen
We present Hubble Space Telescope ultraviolet and optical STIS spectroscopy of the [WCL] planetary nebula central star CPD-568032, obtained during its latest lightcurve minimum. Th…
Temperature Variations from HST Imagery and Spectroscopy of NGC 7009
R. H. Rubin, N. J. Bhatt, R. J. Dufour +8
We present new HST/WFPC2 imagery and STIS long-slit spectroscopy of the planetary nebula NGC 7009. The primary goal was to obtain high spatial resolution of the intrinsic line rati…
