QUINO-MENDOZA, J. A.; PHILLIPS, J. P.  and  RAMOS-LARIOS, G. Mid-Infrared Observations of Planetary Nebulae detected in the GLIMPSE 3D Survey. Rev. mex. astron. astrofis [online]. 2011, vol.47, n.1, pp.31-48. ISSN 0185-1101.

We present mapping, profiles and photometry for 24 planetary nebulae (PNe) detected in the GLIMPSE 3D mid-infrared (MIR) survey of the Galactic plane. The PNe show many of the properties observed in previous studies of these sources, including evidence for longer wave emission from outside of the ionised zones, a likely consequence of emission from polycyclic aromatic hydrocarbons (PAHs) within the nebular photo-dissociation regimes (PDRs). We also note variations in 5.8 µm/4.5 µm and 8.0 µm/4.5 µm flux ratios with distance from the nuclei; present evidence for enhanced MIR emission in the halos of the sources; and note evidence for variations in colour with nebular evolution.

Keywords : infrared [ISM]; ISM [jets and outflows]; planetary nebulae [general].
