- Abstract
Here we present the first Vacuum UltraViolet (VUV) photoabsorption spectra of ice analogues of Pluto and Charon ice mixtures. For Pluto the ice analogue is an icy mixture containing nitrogen (N
2 ), carbon monoxide (CO), methane (CH4 ) and water (H2 O) prepared with a 100:1:1:3 ratio, respectively. Photoabsorption of icy mixtures with and without H2 O were recorded and no significant changes in the spectra due to presence of H2 O were observed. For Charon a VUV photoabsorption spectra of an ice analogue containing ammonia (NH3 ) and H2 O prepared with a 1:1 ratio was recorded, a spectrum of ammonium hydroxide (NH4 OH) was also recorded. These spectra may help to interpret the P-Alice data from New Horizons., (Copyright © 2017 Elsevier B.V. All rights reserved.)- Published
