Ryosuke Nakamura教授の研究室では、太陽系惑星および衛星の表面・大気の化学的・物理的性質を、赤外分光法を用いて解明することを主眼としています。特に、冥王星と衛星カイロンの表面に存在する凍結揮発性物質（メタン、一酸化炭素、窒素など）の分布と状態の解明が進んでいます。高分解能赤外スペクトロスコピーを用いた天体観測を通じて、宇宙環境下での表面プロセスの理解を深めています。

We present the results of the near-infrared spectroscopy of the Pluto-Charon system, conducted in the K band at two different sub-Earth longitudes. The spatially resolved images resulted in separated spectra with a spectral resolution of approximately 530. The spectrum of Charon showed a broad absorption feature at 2 μm during both orbital phases, suggesting a uniform distribution of water ice. In the separated spectrum of Pluto obtained in June, we confirmed the absorption bands of solid methan
