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…
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…
An Orbitrap-based laser desorption/ablation mass spectrometer designed for spaceflight
Ricardo Arevalo, Laura Selliez, Christelle Briois +8
RATIONALE: The investigation of cryogenic planetary environments as potential harbors for extant life and/or contemporary sites of organic synthesis represents an emerging focal po…
Krypton isotopes and noble gas abundances in the coma of comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Hans Balsiger +24
The ROSINA mass spectrometer DFMS on board ESA's Rosetta spacecraft detected the major isotopes of the noble gases argon, krypton, and xenon in the coma of comet 67P/Churyumov-Gera…
