On the Abiotic Origin of Dimethyl Sulfide: Discovery of Dimethyl Sulfide in the Interstellar Medium
Caselli, Paola; Martín, Sergio; Jiménez-Serra, Izaskun +14 more
Following the discovery of dimethyl sulfide (DMS; CH3SCH3) signatures in comet 67P/Churyumov–Gerasimenko, we report the first detection of this organosulfur species in the interstellar medium during the exploration of an ultradeep molecular line survey performed toward the Galactic center molecular cloud G+0.693-0.027 with th…
Primordial Origin of Methane on Eris and Makemake Supported by D/H Ratios
Mousis, Olivier; Werlen, Aaron; Benest Couzinou, Tom +1 more
Deuterium, a heavy isotope of hydrogen, is a key tracer of the formation of the solar system. Recent James Webb Space Telescope observations have expanded the data set of deuterium-to-hydrogen (D/H) ratios in methane on the KBOs Eris and Makemake, providing new insights into their origins. This study examines the elevated D/H ratios in methane on …
Boulder Migration in the Khonsu Region of Comet 67P/Churyumov–Gerasimenko
Shi, Xian; El-Maarry, Mohamed Ramy; Tang, Xiang
The European Space Agency's Rosetta mission is the only space mission that has performed long-term monitoring of a comet at close distances. For over two years, Rosetta rendezvoused with comet 67P/Churyumov–Gerasimenko, which revealed diverse evolutionary processes of the cometary nucleus. One of the most striking events is the migration of a ∼30 …
