Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic Ray Processing
R. Maggiolo, F. Dhooghe, G. Gronoff +2
Spectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO2 enrichment (CO2/H2O = 7.6+-0.3) that is 4.5 sigma above solar system comet trends…
The Effect of Cosmic Rays on Cometary Nuclei: I Dose deposition
G. Gronoff, R. Maggiolo, G. Cessateur +9
Comets are small bodies thought to contain the most pristine material in the solar system. However, since their formation 4.5 Gy ago, they have been altered by different processes.…
Atmospheric Escape Processes and Planetary Atmospheric Evolution
Guillaume Gronoff, Phil Arras, Suleiman M Baraka +17
The habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars dri…
Synthesis of molecular oxygen via irradiation of ice grains in the protosolar nebula
O. Mousis, T. Ronnet, J. I. Lunine +4
Molecular oxygen has been detected in the coma of comet 67P/Churyumov--Gerasimenko with a mean abundance of 3.80 0.85\% by the ROSINA mass spectrometer on board the Rosetta s…
Impact of radiogenic heating on the formation conditions of comet 67P/Churyumov-Gerasimenko
O. Mousis, A. Drouard, P. Vernazza +19
Because of the high fraction of refractory material present in comets, the heat produced by the radiogenic decay of elements such as aluminium and iron can be high enough to induce…
Origin of molecular oxygen in Comet 67P/Churyumov-Gerasimenko
O. Mousis, T. Ronnet, B. Brugger +13
Molecular oxygen has been detected in the coma of comet 67P/Churyumov-Gerasimenko with abundances in the 1-10% range by the ROSINA-DFMS instrument on board the Rosetta spacecraft.…
