Nitrogen- and nitrogen-oxygen-bearing organic molecules in comet 67P/Churyumov-Gerasimenko: An untargeted investigation
N. Hänni, K. Altwegg, D. Baklouti +6
Comets provide a unique window into the history of the Solar System as they carry some of the best-preserved material and make it available to in situ exploration. A milestone in c…
Evidence for Abiotic Dimethyl Sulfide in Cometary Matter
Nora Hänni, Kathrin Altwegg, Michael Combi +5
Technological progress related to astronomical observatories such as the recently launched James Webb Space Telescope (JWST) allows searching for signs of life beyond our Solar Sys…
Spectro-photometric properties of CoPhyLab's dust mixtures
C. Feller, A. Pommerol, A. Lethuillier +8
Objective: In the framework of the Cometary Physics Laboratory (CoPhyLab) and its sublimation experiments of cometary surface analogues under simulated space conditions, we charact…
Oxygen-bearing organic molecules in comet 67P's dusty coma: first evidence for abundant heterocycles
N. Hänni, K. Altwegg, D. Baklouti +6
The puzzling complexity of terrestrial biomolecules is driving the search for complex organic molecules in the Interstellar Medium (ISM) and serves as a motivation for many in situ…
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…
