The Mass of Hot, Shocked CO in Orion: First Observations of the J = 17 Yields J = 16 Transition at 153 Microns.

Abstract

We have observed the Kleinmann-Low Nebula in Orion and detected the J = 17 to J = 16 transition of carbon monoxide at a flux level of 7 x 10 to the -17th power W/sq cm. Our best estimate for the total mass of hot, T approx. 750 K, CO in the nebula is 8 x 10 to the 30th power g. From this value we as sess the total hydrogen mass at this temperature to be approx. 1.5 solar mass. A puzzling apparent deficit of oxygen in the nebula is discussed. Keywords: Abundances; Far infrared; Interferometer; Interstellar molecules; IR spectroscopy; Molecular lines; Orion Nebula. (Author).
