 note = {New spectrum of the Pluto is presented, covering the 2.8-4.1 micrometer wavelength range. The new data show prominent absorptions of ethane ice on surface of Pluto. The present results require the mass ratio of ethane to methane to be approximately 1:10, which is much higher than the value expected from the equilibrium condensation theory. Three processes are proposed to add this surplus ethane to Pluto's surface: 1) external reservoir, 2) internal reservoir, and 3) photolysis/radiolysis. The present study could provide important implications and constraints for evolutions of the edge of the solar system, such as Pluto, Charon, and EKBOs., 資料番号: AA0046650044},
