Helium Recombination Lines as a Probe of Abundance and Temperature Problems
Y. Zhang, R. H. Rubin, X. -W. Liu
The paper presents a simplified formula to determine an electron temperature, Te(He I), for planetary nebulae (PNe) using the He I 7281/6678 line flux ratio. In our previous studie…

MOCASSIN: 3D photoionisation and dust radiative transfer modelling of PNe
Barbara Ercolano, M. J. Barlow, P. J. Storey +1
We present the first 3D Monte Carlo photoionisation code to include a fully self-consistent treatment of dust radiative transfer (RT) within the photoionised region. This is the la…

Water Ice, Silicate and PAH Emission Features in the ISO Spectrum of the Carbon-rich Planetary Nebula CPD-56 8032
Martin Cohen, M. J. Barlow, R. J. Sylvester +5
Combined ISO SWS and LWS spectroscopy is presented of the late WC-type planetary nebula nucleus CPD-56 8032 and its carbon-rich nebula. The extremely broad coverage (2.4-197 micron…
