Molecular line survey of NGC 7027

Abstract

We report preliminary results of a spectral line survey of NGC 7027 in the λ 3 mm and 1.3 mm bands using the Arizona Radio Observatory (ARO) 12-m and 10-m telescopes. To a sensitivity limit of ∼10-20 mK, we have detected 34 lines, including hydrogen recombination lines and rotational transitions of ON, CO, CCH, CO+, HCO+, and their isotopes. © 2006 International Astronomical Union.
