Research Abstract

Comets consist of primordial icy materials and refractory dust grains. Comets are considered to be pristine objects that provide precious clues about the formation of the solar system. In this study, we observed comets in near-and mid-infrared wavelengths using the Subaru telescope and the infrared satellite AKARI. We derived the relative abundances of crystalline silicate in dust grains and carbon dioxide in cometary ice for more than 10 comets.
