Dust of comet 67P/Churyumov-Gerasimenko collected by Rosetta/MIDAS: classification and extension to the nanometre scale
T. Mannel, M. S. Bentley, P. D. Boakes +9
The properties of the smallest subunits of cometary dust contain information on their origin and clues to the formation of planetesimals and planets. Compared to IDPs or particles…
Dome C UltraCarbonaceous Antarctic MicroMeteorites Infrared and Raman fingerprints
E. Dartois, C. Engrand, J. Duprat +5
UltraCarbonaceous Antarctic MicroMeteorites (UCAMMs) represent a small fraction of interplanetary dust particles reaching the Earth's surface and contain large amounts of an organi…
Cross sections relevant to gamma-ray line emission in solar flares: He-induced reactions on O nuclei
V. Tatischeff, J. Duprat, J. Kiener +12
Gamma-ray production cross sections have been measured for gamma-ray lines copiously emitted in the He bombardment of O nuclei: the 937, 1042 and 1081 keV lines of $^{18…
Identification of organic molecules with a laboratory prototype based on the Laser Ablation-CosmOrbitrap
L. Selliez, C. Briois, N. Carrasco +18
In the Solar System, extra-terrestrial organic molecules have been found on cometary primitive objects, on Titan and Enceladus icy moons and on Mars. Identification could be achiev…
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…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
