Research Abstract

Comets are the remnants of planetesimals formed in the early solar system 4.6 giga-years ago. Present sources of comets are the Oort cloud and the Kuiper-belt far from the Sun. However, the original birth place of the comets are thought to be inner region than those dynamical sources. Comets originated in different sources are formed in different birth areas. Especially, comets originated in the Kuiper-belt played an important role to deliver the pre-biotic molecules into the early Earth. This program are focused on the organic molecules in Kuiper-belt comets. Based on our survey, organic molecules are depleted in the comets originated in Kuiper-belt.
