Gas mixing through a Smoothed Particle Hydrodynamics approach
Luca Maggioni, Matteo Teodori, Gianfranco Magni +3
Transport and mixing of gas species are of particular interest in planetary environments, where interactions among multiple species can occur within confined or porous media. In th…
Identification of Ammonium Salts on Comet 67P/C-G Surface from Infrared VIRTIS/Rosetta Data Based on Laboratory Experiments. Implications and Perspectives
Olivier Poch, Istiqomah Istiqomah, Eric Quirico +29
The nucleus of comet 67P/Churyumov-Gerasimenko exhibits a broad spectral reflectance feature around 3.2 m, which is omnipresent in all spectra of the surface, and whose attribut…
Ceres as seen by VIR/ Dawn: spectral modeling and laboratory measurements suggest altered and pristine silicates within carbon chemistry
Andrea Raponi, Marco Ferrari, Maria Cristina De Sanctis +3
The NASA/Dawn mission has acquired an unprecedented amount of data from the surface of the dwarf planet Ceres, providing a thorough characterization of its surface composition. The…
Correction of the VIR-visible data set from the Dawn mission at Vesta
B. Rousseau, M. C De Sanctis, A. Raponi +7
This work describes the correction method applied to the dataset acquired at the asteroid (4) Vesta by the visible channel of the visible and infrared mapping spectrometer. The ris…
Infrared detection of aliphatic organics on a cometary nucleus
A. Raponi, M. Ciarniello, F. Capaccioni +28
The ESA Rosetta mission has acquired unprecedented measurements of comet 67/P-Churyumov-Gerasimenko (hereafter 67P) nucleus surface, whose composition, as determined by in situ and…
Thermal convection in the crust of the dwarf planet (1) Ceres
M. Formisano, C. Federico, J. Castillo-Rogez +2
Ceres is the largest body in the Main Belt, and it is characterized by a large abundance of water ice in its interior. This feature is suggested by its relatively low bulk density…
Ammonium salts are a reservoir of nitrogen on a cometary nucleus and possibly on some asteroids
O. Poch, I. Istiqomah, E. Quirico +29
The measured nitrogen-to-carbon ratio in comets is lower than for the Sun, a discrepancy which could be alleviated if there is an unknown reservoir of nitrogen in comets. The nucle…
Correction of the VIR-Visible data set from the Dawn mission
B. Rousseau, A. Raponi, M. Ciarniello +6
Data acquired at Ceres by the visible channel of the Visible and InfraRed mapping spectrometer (VIR) on board the NASA Dawn spacecraft are affected by the temperatures of both the…
Diurnal variation of dust and gas production in comet 67P/Churyumov-Gerasimenko at the inbound equinox as seen by OSIRIS and VIRTIS-M on board Rosetta
C. Tubiana, G. Rinaldi, C. Güttler +53
On 27 Apr 2015, when 67P/C-G was at 1.76 au from the Sun and moving towards perihelion, the OSIRIS and VIRTIS-M instruments on Rosetta observed the evolving dust and gas coma durin…
VIRTIS-H observations of comet 67P's dust coma: spectral properties and color temperature variability with phase and elevation
D. Bockelée-Morvan, C. Leyrat, S. Erard +14
We analyze 2-5 micrometre spectroscopic observations of the dust coma of comet 67P/Churyumov-Gerasimenko obtained with the VIRTIS-H instrument onboard Rosetta from 3 June to 29 Oct…
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…
