Photoionization models for planetary nebulae with inhomogeneous chemical composition
Considering the prototypical case of NGC 6153, it is shown that photoionization models comprising two com-ponents with di erent chemical compositions can account quantitatively for most of the spectral features ofthose planetary nebulae in which the optical recombination lines seem to indicate abund...
