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…
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…
Detection of volatiles undergoing sublimation from 67P/Churyumov-Gerasimenko coma particles using ROSINA/COPS. II. The nude gauge
Boris Pestoni, Kathrin Altwegg, Hans Balsiger +5
In an earlier study, we reported that the ram gauge of the COmet Pressure Sensor (COPS), one of the three instruments of the Rosetta Orbiter Spectrometer for Ion and Neutral Analys…
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…
Detection of volatiles undergoing sublimation from 67P/Churyumov-Gerasimenko coma particles using ROSINA/COPS. I. The ram gauge
Boris Pestoni, Kathrin Altwegg, Hans Balsiger +5
The ESA Rosetta mission has allowed an extensive in-situ study of comet 67P/Churyumov-Gerasimenko. In measurements performed by the ram gauge of the on-board COmet Pressure Sensor…
Molecule dependent oxygen isotopic ratios in the coma of comet 67P/Churyumov-Gerasimenko
K. Altwegg, H. Balsiger, M. Combi +9
The ratios of the three stable oxygen isotopes 16O, 17O and 18O on Earth and, as far as we know in the solar system, show variations on the order of a few percent at most, with a f…
