  • Abstract High-resolution spectra of Pluto in the 1.66 μm region, recorded with the VLT/CRIRES instrument in 2008 (2 spectra) and 2012 (5 spectra), are analyzed to constrain the spatial and vertical distribution of methane in Pluto’s atmosphere and to search for mid-term (4 year) variability. A sensitivity study to model assumptions (temperature structure, surface pressure, Pluto’s radius) is performed. Results indicate that (i) no variation of the CH 4 atmospheric content (column-density or… CONTINUE READING
