Evidence of ammonium salts in comet 67P as explanation for the nitrogen depletion in cometary comae
K. Altwegg, H. Balsiger, J. -J. Berthelier +14
Cometary comae are generally depleted in nitrogen. The main carriers for volatile nitrogen in comets are NH3 and HCN. It is known that ammonia readily combines with many acids like…
The Surface Distributions of the Production of the Major Volatile Species, H2O, CO2, CO and O2, from the Nucleus of Comet 67P/Churyumov-Gerasimenko throughout the Rosetta Mission as Measured by the ROSINA Double Focusing Mass Spectrometer
Michael Combi, Yinsi Shou, Nicolas Fougere +12
The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) suite of instruments operated throughout the over two years of the Rosetta mission operations in the vicinity…
Three-Dimensional Modeling of Callisto's Surface Sputtered Exosphere Environment
Audrey Vorburger, Martin Pfleger, Jesper Lindkvist +6
We study the release of various elements from Callisto's surface into its exosphere by plasma sputtering. The cold Jovian plasma is simulated with a 3D plasma-planetary interaction…
The evolution of the electron number density in the coma of comet 67P at the location of Rosetta from 2015 November through 2016 March
Erik Vigren, Niklas J. T. Edberg, Anders I. Eriksson +6
A comet ionospheric model assuming the plasma to move radially outward with the same bulk speed as the neutral gas and not being subject to severe reduction through dissociative re…
Elemental and molecular abundances in comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Hans Balsiger +18
Comets are considered to be some of the most pristine and unprocessed solar system objects accessible to in-situ exploration. Investigating their molecular and elemental compositio…
Volatile species in comet 67P/Churyumov-Gerasimenko -- investigating the link from the ISM to the terrestrial planets
Martin Rubin, David V. Bekaert, Michael W. Broadley +2
Comets contain abundant amounts of organic and inorganic species. Many of the volatile molecules in comets have also been observed in the interstellar medium and some of them even…
