New experimental studies of ice grain ejection by massive gas flow, implications to comets, Enceladus, Triton and Mars

Abstract

Abstract. Ice grains are ejected whenever gases are flowing from gasladen amorphous ice upon its warming-up. We elucidated the mechanism of gas trapping when flowing onto a gas-free ice layer. The observations on ice grain ejection from comets, Enceladus, Triton and the Martian South Polar region are explained as well.
