Pre-accretional irradiation of comet 67P/Churyumov-Gerasimenko constituents
Inès Sansberro, Nicolas Fray, Hervé Cottin +11
Comets are thought to have largely preserved the primordial material from which they formed. Therefore, cometary studies provide important clues about the processes involved in the…
The detection of solid phosphorus and fluorine in the dust from the coma of comet 67P/Churyumov-Gerasimenko
Esko Gardner, Harry J. Lehto, Kirsi Lehto +7
Here, we report the detection of phosphorus and fluorine in solid particles collected from the inner coma of comet 67P/Churyumov-Gerasimenko measured with the COmetary Secondary Io…
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…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
Identification of organic molecules with a laboratory prototype based on the Laser Ablation-CosmOrbitrap
L. Selliez, C. Briois, N. Carrasco +18
In the Solar System, extra-terrestrial organic molecules have been found on cometary primitive objects, on Titan and Enceladus icy moons and on Mars. Identification could be achiev…
