- Mid-Infrared Observations of Planetary Nebulae detected in the GLIMPSE 3D Survey J. A. Quino-Mendoza J. P. Phillips G. Ramos-Larios Física, Astronomía y Matemáticas ISM general Infrared jets and outflows planetary nebulae 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. 2011 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57119922003 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Num.1 Vol.47
