Sublimation rates of carbon monoxide and carbon dioxide from comet nuclei at large distances from the Sun [PDF]
One of the more attractive among the plausible scenarios for the major emission event recently observed on Comet Halley at a heliocentric distance of 14.3 AU is activation of a source of ejecta driven by an icy substance much more volatile than water. As
