摘要

Here we report a infrared high-resolution spectroscopy of Pluto in the L band. The spectroscopic observation was performed by the Subaru telescope with the adaptive optics system. The spectrum is dominated by the strong and broad absorption features of methane, but includes some additional features. Comparing the spectrum with model calculations, we suggest that absorption features could be an indication of nonmethane hydrocarbons on Pluto’s surface.
