Figure 2:
Reflectance spectra of TNOs 2003 UB313, 2005 FY9,
and Pluto shifted vertically, in the two wavelength regions
of the most prominent
CH4 ice absorption bands.
Upper: (A) is the spectrum
of 2003 UB313 and overplotted (dashed lines) is the spectrum of pure
methane ice grains of 1.5 cm diameter; (B) is the spectrum of 2005 FY9 and overplotted (dashed lines) the spectrum of pure
methane ice grains of 4.5 cm diameter; (C) is the spectrum of Pluto and
overplotted (dashed lines) the spectrum of pure
methane ice grains of 500 m diameter; vertical dashed lines
indicate the central position of pure
methane ice bands (Grundy et al. 2002).
Lower: (A) same as in upper figure; (B) is the spectrum of
2005 FY9 and overplotted (dashed lines) the spectrum of pure
methane ice grains of 2.5 cm diameter; (C) as in upper figure. |
