反応速度論から探る隕石有機物の起源と進化

抄録

I have been studying origin and evolution of extraterrestrial organic matter on the basis of experimental kinetic approaches that enable us to predict changes in its molecular structure and chemistry during parent body processes. Here I summarize experimental studies of organic solid formations starting from formaldehyde and ammonia with the presence of liquid water, and decreasing in aliphatic C–H bonds as observed in infrared spectra with heating experiments of Murchison meteorite. The related works are also reviewed and the applications for deciphering thermal histories of asteroids are discussed.
