The Galactic disc distribution of planetary nebulae with warm dust emission features - I
We investigate the Galactic disc distribution of a sample of planetary nebulae characterized in terms of their mid-infrared spectral features. The total number of Galactic disc PNe with 8-13 μm spectra is brought up to 74 with the inclusion of 24 new objects, the spectra of which we present for the...
