Report of the Terrestrial Bodies Science Working Group. Volume 8: The comets [PDF]
The determination of the nuclear and atmospheric properties of comets, and the interaction of the solar wind with the comet tail are scientific objectives for a mission to one or more comets in the next decade.

The 10 micron spectral structure in comets [PDF]
The 10 micron spectra of comets Halley (1982i), Wilson (1986l), Kohoutek (1973f) and Bradfield (1987s) are presented and compared. The silicate emission profiles of Halley and Bradfield are seen to be remarkably similar in that both contain a sharp break

Comparison of the 3.36 micrometer feature to the ISM [PDF]
It has been noted that the 3.36 micrometer emission feature is not the same as that of any ISM band at 3.4 micrometer. This is documented herein. There is no convincing analog to the cometary 3.36 micrometer emission feature seen in the Interstellar ...

Polarimetric observations of comet Levy 1990c and of other comets: Some clues to the evolution of cometary dust [PDF]
The evolution with the phase angle alpha of the polarization degree P of light scattered by comet Halley's dust is well documented. No significant discrepancy is found between Halley and Levy polarization curves near the inversion point.
