Spectral Diversity among the Nuclei of Comets
Icarus, 1993Abstract The spectral characteristics of cometary nuclei are poorly known. To help rectify this situation, we have been obtaining spectra of cometary nuclei when they are favorably located, i.e., sufficiently far from the Sun that little cometary activity remains.

MASS FLUX OF ASTEROIDAL ORIGIN METEOROIDS ON PERIODIC COMET NUCLEI
Earth, Moon, and Planets, 2004We examine the potential contamination of cometary nuclei through impacts from asteroidal origin meteoroids. The paper uses a simple model and has the goal of determining whether asteroidal contamination is potentially significant. We assume a meteoroid power law mass distribution with index values in the range from s=1.83 to s=2.09.

Meteoroid impact into short-period comet nuclei
Nature, 1981The effects of extended meteoroid bombardment on short-period comet nuclei are examined and their possible implications for asteroid and meteorite studies are discussed. It is suggested that after devolatilization of the nucleus, the accumulated material might combine with primary cometary solids to produce environments conducive to the formation of ...
