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…
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…
Non-resonant Alfvénic instability activated by high temperature of ion beams in compensated-current astrophysical plasmas
Pavlo Malovichko, Yuriy Voitenko, Johan De Keyser
Context: Compensated-current systems are established in response to hot ion beams in terrestrial foreshock regions, around supernova remnants, and in other space and astrophysical…
Evidence for depletion of heavy silicon isotopes at comet 67P/Churyumov-Gerasimenko
M. Rubin, K. Altwegg, H. Balsiger +17
Context. The Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) was designed to measure the composition of the gas in the coma of comet 67P/Churyumov-Gerasimenko, t…
Characteristics of the flankmagnetopause: Cluster observations
S. Haaland, J. Reistad, P. Tenfjord +6
The magnetopause is a current sheet forming the boundary between the geomagnetic field on one side and the shocked solar wind on the other side. This paper discusses properties of…
