Title: | NEW STRUCTURES FOUND IN WISE IMAGING OF PLANETARY NEBULAE |
Topic: | Discoveries |
Abstract: | We report the discovery of new structures in a series of planetary nebulae found in Wide-Field Infrared Survey Explorer (WISE) imaging. The data presented here reveal mainly the dust emission distribution and unexpected features, like haloes and filamentary structures. One of the most impressive objects (IC418, Ramos Larios et al. 2012) posses two detached haloes with sizes around 200 arcsec, and whose elliptical morphology and asymmetrical brightness distribution of this outer halo may be indicative of the motion of IC418 relative to the interstellar medium. |
