Complex organosulfur molecules on comet 67P: Evidence from the ROSINA measurements and insights from laboratory simulations

Ehlmann, Bethany L.; Brown, Michael E.; Choukroun, Mathieu +9 more

The ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) instrument aboard the Rosetta mission revolutionized our understanding of cometary material composition. One of Rosetta's key findings is the complexity of the composition of comet 67P/Churyumov-Gerasimenko. Here, we used ROSINA data to analyze dust particles that were volatili…
