| Abstract | We present the result of photo-ionizing modelling of the three planetary nebulae (PNe) A 20, A 15 and MeWe 1-3. All three objects are roughly roundish, highly excited and have a high galactic z. The PNe displayed low densities in the shell, but relatively dense halos. A low metallicity and a relative high electron temperature were found. Comparisons with radio observations confirmed the obtained properties. The objects are very likely originating from thick disk stellar progenitors. The distances found investigating the PNe shells are somewhat lower than those derived spectroscopically with the central stars in the past. |
