彗星由原始的冰质物质和难熔的尘埃颗粒组成。彗星被认为是原始天体,为太阳系的形成提供了宝贵的线索。在这项研究中,我们使用斯巴鲁望远镜和红外卫星AKARI观测了近红外和中红外波长的彗星。我们导出了10多颗彗星尘埃颗粒中结晶硅酸盐和彗星冰中二氧化碳的相对丰度。
英文摘要
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.
