Research Abstract

We obtained three main results in this project. First is on the molecular compositions of impact-induced planetary atmospheres. Calculation results revealed that Venus and super Earth's around M-type stars would have CO-H2-rich atmosphere and Mars and Earth would have CH4-rich atmosphere.Second is on hydrogen escape rate from terrestrial planets. Calculation results indicate that hydrogen escape rate depends greatly on whether or not a steam atmosphere would condense to an ocean after accretion and determines whether an Earth-like wet planet or Venus-like dry planet, including its interior, would form. Third is impact experiments and mass spectroscopic measurements of impact-degassed volatiles. Experimental results show that the K/Pg impact would generate acid rain sufficient to acidify the ocean surface layer, which may lead to the K/Pg mass extinction.
