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…
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…
The ALMA-PILS survey: First detection of the unsaturated 3-carbon molecules Propenal (CHCHO) and Propylene (CH) towards IRAS 162932422 B
S. Manigand, A. Coutens, J. -C. Loison +11
Complex organic molecules with three carbon atoms are found in the earliest stages of star formation. In particular, propenal (CHCHO) is a species of interest due to its im…
CHO-bearing molecules in Comet 67P/Churyumov-Gerasimenko
Markus Schuhmann, Kathrin Altwegg, Hans Balsiger +10
In 2004, the Rosetta spacecraft was sent to comet 67P/Churyumov-Gerasimenko for the first ever long-term investigation of a comet. After its arrival in 2014, the spacecraft spent m…
The ALMA-PILS survey: Inventory of complex organic molecules towards IRAS 16293-2422 A
S. Manigand, J. K. Jørgensen, H. Calcutt +6
Complex organic molecules (COM) are detected in many sources in the warm inner regions of envelopes surrounding deeply embedded protostars. Exactly how these COM form remains an op…
