The temporal evolution of exposed water ice-rich areas on the surface of 67P/Churyumov-Gerasimenko: spectral analysis
A. Raponi, M. Ciarniello, F. Capaccioni +16
Water ice-rich patches have been detected on the surface of comet 67P/Churyumov-Gerasimenko by the VIRTIS hyperspectral imager on-board the Rosetta spacecraft, since the orbital in…
Evolution of CO, CH, and OCS abundances relative to HO in the coma of comet 67P around perihelion from Rosetta/VIRTIS-H observations
D. Bockelée-Morvan, J. Crovisier, S. Erard +19
Infrared observations of the coma of 67P/Churyumov-Gerasimenko were carried out from July to September 2015, i.e., around perihelion (13 August 2015), with the high-resolution chan…
Detection of exposed HO ice on the nucleus of comet 67P/Churyumov-Gerasimenko
M. A. Barucci, G. Filacchione, S. Fornasier +42
Since the orbital insertion of the Rosetta spacecraft, comet 67P/Churyumov-Gerasimenko (67P/C-G) has been mapped by OSIRIS camera and VIRTIS spectro-imager, producing a huge quanti…
The global surface composition of 67P/CG nucleus by Rosetta/VIRTIS. I) Prelanding mission phase
Gianrico Filacchione, Fabrizio Capaccioni, Mauro Ciarniello +27
From August to November 2014 the Rosetta orbiter has performed an extensive observation campaign aimed at the characterization of 67P/CG nucleus properties and to the selection of…
Saturn's icy satellites investigated by Cassini - VIMS. IV. Daytime temperature maps
Gianrico Filacchione, Emiliano D'Aversa, Fabrizio Capaccioni +13
The spectral position of the 3.6 micron continuum peak measured on Cassini-VIMS I/F spectra is used as a marker to infer the temperature of the regolith particles covering the surf…
