(Ed.), "Planetary nebulae in the GLIMPSE survey", Proceedings of the International Astronomical Union, Symposium #234, Planetary Nebulae in our Galaxy and Beyond, Cambridge: Cambridge University Press, 2 (S234), ss. 445-6, Bibcode:2006IAUS..234..445K, doi:10.1017/S1743921306003668Özgürce erişilebilir, Planetary nebulae (PNs) have high dust content and radiate strongly in the infrared. For young PNs, the dust component accounts for about one third of the total energy output of the nebulae (Zhang & Kwok 1991). The typical color temperatures of PNs are between 100 and 200 K, and at λ >5 μm, dust begins to dominate over bound-free emission from the ionized component. Although PNs are traditionally discovered through examination of photographic plates or Hα surveys, PNs can also be identified in infrared surveys by searching for red objects with a rising spectrum between 4–10 μm.
