L., Discovery of Multiple Coaxial Rings in the Quadrupolar Planetary Nebula NGC 6881, The Astrophysical Journal, December 2005, 635 (1): L49–52, Bibcode:2005ApJ...635L..49K, doi:10.1086/499332, We report the discovery of multiple two-dimensional rings in the quadrupolar planetary nebula NGC 6881. As many as four pairs of rings are seen in the bipolar lobes, and three rings are seen in the central torus. While the rings in the lobes have the same axis as one pair of the bipolar lobes, the inner rings are aligned with the other pair. The two pairs of bipolar lobes are likely to be carved out by two separate high-velocity outflows from the circumstellar material left over from the asymptotic giant branch (AGB) wind. The two-dimensional rings could be the results of dynamical instabilities or the consequence of a fast outflow interacting with remnants of discrete AGB circumstellar shells.

H. , 編, 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), 2006, 2 (S234): 445–6, Bibcode:2006IAUS..234..445K, doi:10.1017/S1743921306003668, Planetary nebulae (PNs) have high dust content and radiate strongly in the infrared. For young PNs, the dust component accounts for ∼1/3 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.
