[40P.10] HCN and CO Emission in comet C/1997 N1 (Tabur)

M. Spinar, M. Womack, M. Goldschen (St. Cloud State Univ.)

Mm-wavelength spectra were obtained of HCN and CO using the NRAO 12-m telescope during 1996 Oct. The HCN J=1-0 transition at 89 GHz was detected on Oct 6-7 UT with an integrated line-flux area of 0.07 +/- 0.01 K km s-1, a FWHM linewidth of 1.5 ± 0.2 km s-1, and the line center is not measurably shifted from the ephemeris velocity. The CO J=1-0 line was not detected down to a 3-sigma level of 0.04 K km s-1. We will present spectra and a production rate for HCN, and an upper limit to the CO production rate.
