Research Abstract

The composition ratio of the volatiles in comets, the relics of our solar system, is contains the temperature environment in the proto planetary disk of solar system and information on the matter transport, and becomes a clue that searches for the variation of present cometary activities. While carbon dioxide is thought as one of major element of the volatile of comet after water, it is difficult to observe it directly by ground-based observation. This study succeeded in expanding sample of carbon dioxide to water ratio based on oxygen forbidden lines that appeared in the spectrum of the visible region, by analyzing the archive data of the ground-based observation again.
