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…
Volatiles in the HO and CO ices of comet 67P/Churyumov-Gerasimenko
Martin Rubin, Kathrin Altwegg, Jean-Jacques Berthelier +11
ESA's Rosetta spacecraft at comet 67P/Churyumov-Gerasimenko (67P) was the first mission that accompanied a comet over a substantial fraction of its orbit. On board was the ROSINA m…
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…
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…
