Photo-ionization modelling of planetary nebulae -- II. Galactic bulge nebulae, a comparison with literature results
P. A. M. van Hoof, G. C. Van de Steene
We have constructed photo-ionization models of five galactic bulge planetary nebulae using our automatic method which enables a fully self-consistent determination of the physical…
