Vaporization in Comets - the Icy Grain Halo of Comet West
Abstract
The variation with heliocentric distance of the production rates of various species in Comet West (1975n=1976 VI) is explained with a cometary model consisting of a CO2-dominated nucleus plus a halo of icy grains of H2O or clathrate hydrate. We conclude that the parents of CN and C3 are released primarily from the nucleus but that the parent of C2 is released primarily from the halo of icy grains.
