Multi-instrument analysis of 67P/Churyumov-Gerasimenko coma particles: COPS-GIADA data fusion
Boris Pestoni, Kathrin Altwegg, Vincenzo Della Corte +6
The European Space Agency's Rosetta mission to comet 67P/Churyumov-Gerasimenko has offered scientists the opportunity to study a comet in unprecedented detail. Four instruments of…
Abundant ammonium hydrosulphide embedded in cometary dust grains
K. Altwegg, M. Combi, S. A. Fuselier +7
Ammonium hydrosulphide has long since been postulated to exist at least in certain layers of the giant planets. Its radiation products may be the reason for the red colour seen on…
High D/H ratios in water and alkanes in comet 67P/Churyumov-Gerasimenko measured with the Rosetta/ROSINA DFMS
Daniel R. Müller, Kathrin Altwegg, Jean-Jacques Berthelier +8
Isotopic abundances in comets are key to understanding the history and origin of material in the Solar System. Deuterium-to-hydrogen (D/H) ratios in water are available for several…
Refractory elements in the gas phase for comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Jean-Jacques Berthelier +10
Results. We found that gas-phase silicon was present throughout the Rosetta mission. Furthermore, the presence of sodium and iron atoms near the comet's perihelion confirms that sp…
Cyanogen, cyanoacetylene, and acetonitrile in comet 67P and their relationship to the cyano radical
N. Hänni, K. Altwegg, H. Balsiger +6
The cyano radical (CN) is one of the most frequently remotely observed species in space, also in comets. Data from the high-resolution Double Focusing Mass Spectrometer (DFMS) on b…
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…
