Abstract:
High-resolution and high signal-to-noise ratio spectra of Comet C/1995
O1 (Hale-Bopp), which provided continuous wavelength coverage from
5500Å to 8500Å and partial coverage from 4000Å to 5500Å,
were obtained with the Coude Echelle Spectrograph at Beijing
Astronomical Observatory on March 26, 28 and April 22, 1997. In the
spectra we found 532 emission features, among which 459 lines
from H, O, Na, C2, C3, CN, CH, NH2 and H2O+ were identified.
The intensity of sodium emission lines at 5890 Å and 5896 Å on
April 22 increased about 5 fold compared to that recorded on March 26
and 28. The intensity ratio
Iλ5577/(Iλ6300+Iλ6364) of [O I] is
consistent with the formation of excited O atoms from the
photodissociation of H2O.
