Research Abstract

In this research project, we studied chemical reaction processes that occur during hypervelocity impacts of carbon-rich meteoritic bodies to primordial Earth with an N2-rich atmosphere. Band-filter imaging observations of impact experiments simulating such meteoritic collisions allowed us quantitatively describe the processes that hot impact fragments evaporates to organic gas and form CN radical through reaction with a surrounding N_2-rich atmosphere. Analyses of final gas product have revealed that significant amounts of HCN are produced, strongly suggesting that cyanic compounds, which are stable in room temperature and pressure and important in the origin of life, can be synthesized by meteoritic impacts.
