First in-situ detection of the CN radical in comets and evidence for a distributed source
Nora Hänni, Kathrin Altwegg, Boris Pestoni +4
Although the debate regarding the origin of the cyano (CN) radical in comets has been ongoing for many decades, it has yielded no definitive answer to date. CN could previously onl…
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…
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…
A comparison between the two lobes of comet 67P/Churyumov-Gerasimenko based on D/H ratios in H2O measured with the Rosetta/ROSINA DFMS
Isaac R. H. G. Schroeder, Kathrin Altwegg, Hans Balsiger +13
The nucleus of the Jupiter-family comet 67P/Churyumov-Gerasimenko was discovered to be bi-lobate in shape when the European Space Agency spacecraft Rosetta first approached it in J…
