    • 8-13 mu m dust emission features in Galactic bulge planetary nebulae 
      Casassus Montero, Simón; Roche, P. F.; Aitken, D. K.; Smith, C. H. (BLACKWELL SCIENCE LTD, 2001-11-01)
      A sample of 25 infrared-bright planetary nebulae (PNe) towards the Galactic bulge is analysed through 8-13 mum spectroscopy. The classification of the warm dust emission features provides a measure of the C/O chemical ...
    • The Galactic disc distribution of planetary nebulae with warm dust emission features - I 
      Casassus Montero, Simón; Roche, P. F.; Aitken, D. K.; Smith, C. H. (BLACKWELL SCIENCE LTD, 2001-02-01)
      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 mum spectra is brought up to ...
