Three-dimensional chemically homogeneous and bi-abundance photoionization models of the "super-metal-rich" planetary nebula NGC 6153
H. -B. Yuan, X. -W. Liu, D. Péquignot +3
Deep spectroscopy of the planetary nebula (PN) NGC\,6153 shows that its heavy element abundances derived from optical recombination lines (ORLs) are ten times higher than those der…

Helium recombination spectra as temperature diagnostics for planetary nebulae
Y. Zhang, X. -W. Liu, Y. Liu +1
Electron temperatures derived from the \ion{He}{1} recombination line ratios, designated (\ion{He}{1}), are presented for 48 planetary nebulae (PNe). We study the effect…
