Destruction of Dirty Ice Mantles by Sputtering
Published online by Cambridge University Press: 14 August 2015
Abstract
Dirty ice mantles are destroyed efficiently by sputtering of He atoms when clouds encounter shock velocities greater than 13–15 km s–1. Destruction due to grain-grain collisions is found to be about 10–3 times less efficient. Sputtering in the hot intercloud medium should make intercloud grains smaller than cloud grains.
