Journal Article · · Astrophys. J.; (United States)
DOI:https://doi.org/10.1086/160730· OSTI ID:6239797
New observations of the ultraviolet spectrum of HD 44179 are reported. Absorption due to the CO molecule is present in the spectrum, with N/sub CO/ roughly-equal10/sup 18/ cm/sup -2/. Emission due to either CO or a molecule containing CequivalentC, CequivalentN, C-C, and C-H bonds (or both) is also present.
