Abstract

Ethane (C₂H₆) and water (H₂O) were detected in comet 2002 C1 Ikeya-Zhang on seven dates post-perihelion between UT 2002 March 21.9 (R_h = 0.51 AU) and April 13.9 (R_h = 0.78 AU), using the Cryogenic Echelle Spectrometer (CSHELL) at the NASA Infrared Telescope Facility. Our long-slit spectra featured both high spectral dispersion and high spatial resolution about the nucleus, permitting the extraction of rotational temperatures (for H₂O), production rates, and spatial information along the slit. Here we present results for H₂O and C₂H₆ on one date (April 13.7-13.9). Average production rates on this date are Q(H₂O) = (2.1 ± 0.3) × 10²⁹ molecules s^-1, and Q(C₂H₆) = (1.3 ± 0.2) × 10²⁷ molecules s^-1, giving a mixing ratio of C₂H₆ / H₂O = (6.2 ± 1.3) × 10^-3.
