Narrowband Near-Infrared Imaging of Young Planetary Nebulae and Transition Objects: Probing Core and Halo Structures

Abstract

The new images presented here have high spatial resolution and are very sensitive to low levels of emission. We compare our new data to existing imaging and spectroscopic data to give clues as to the structure and formation of planetary nebulae, the role of shocks, and the evolution of photon-dominated regions.
