3 micron spectrophotometry of Comet Halley - evidence for water ice

Journal Article · · Astrophys. J.; (United States)
DOI:https://doi.org/10.1086/166896· OSTI ID:6438101
Structure has been observed in the 3-3.6 micron preperihelion spectrum of Comet Halley consistent with either an absorption band near 3.1 microns or emission near 3.3 microns. The results suggest that a large fraction of the water molecules lost by the comet are initially ejected in the form of small ice particles rather than in the gas phase. 24 references.
