Аннотация:Chemical composition of impact-produced clouds during meteor events on Enceladus is studied.
Small deuterium enrichment, on about 10 %, in surface water ice on the surface of Enceladus can occur due to preferred loss of lighter species to the open space during impact events.
Such values of enrichment factor are not sufficient to explain differences in the D/H ratio between Titan and Enceladus.
Thus, hypothesis of formation of water on Titan and Enceladus from the same reservoir is not confirmed, for this reason formation of water on Enceladus is probably connected with other regions of the nebula than region of formation of Titan.
