Observations of the Far-Infrared Emission Lines of OI and CII in Planetary Nebulae
Abstract
The authors have made observations of the far-infrared, fine structure emission lines [O I] 63 μm, [O I] 145 μm, and [C II] 158 μm in the protoplanetary nebulae AFGL 2688 and AFGL 618, and the classical planetary nebulae IC 418 and NGC 7027. The observations were made with the UC Berkeley tandem Fabry-Perot spectrometer aboard the Kuiper Airborne Observatory in October, 1983.
