The Structure of the Planetary Nebula IC 2149: A Jet or an Edge-On Ring?
Abstract
A set of optical and radio observations of the peculiar planetary nebula (PN) IC 2149 is presented. A bow-shock-like feature towards the NE edge is first detected with the VLA-A, and is also confirmed with HST archive images. Optical spectroscopy leads to apparently contradictory results, leaving this object as a unique case among the planetary nebulae.
