HIGH RESOLUTION OPTICAL SPECTRA OF COMET C/1995 O1(HALE-BOPP)

摘要

High resolution, high signal-to-noise ratio spectra of Comet C/1995 O1 (Hale-Bopp) which provided continuous wavelength coverage from 5500(A) to 8500(A) and partial coverage from 4000(A)to 5500(A) were obtained with Coudé Echelle Spectrograph at Beijing Astronomical Observ atory on March 26, 28 and April 22, 1997. In the spectra we found 751 emission features among which 577 lines from H, O, Na, C2, C3, CN, CH, NH2, H2O+ were identified.
