 note = {The escape timescale of an atmosphere heated by a giant impact to an extremely high temperature was calculated. A large amount of vaporized silicate suppresses the escape flux of hydrogen at the surface temperature higher than 4,000 K. Thus, escape timescale of hydrogen is longer than 10(exp 6) years. At 2,000 to 4,000 K, the heavy gases (e.g., H2O, CO2, CO, N2), which are thought to be contained in a proto-atmosphere, suppress the escape flux of hydrogen. For example, when the mean molecular weight is 10 g/mol, the escape timescale of hydrogen is longer than 10(exp 6) years. Since the planetary surface and/or planetary body cools down to 2,000 K within 10(exp 6) years, giant-impact-induced hydrodynamic escape is unlikely for a proto-atmosphere., 資料番号: AA0046650008},
